DEPARTMENT OF ELECTRONICS & TELECOMMUNICATION ENGG.

start of this semester and year 2017 with Gandharva and Perception brought joyous mood among the students and large number of students participated actively in Gandharva and Perception events. I congratulate to all prize winners and participants. Our students also participated in Firodiya Karandak and were in the finals. Congratulations to entire Avishkar group for their consistent efforts.

Department has organized industrial visits this semester also. Students enjoyed visiting “Akashwani” transmission center, final year students visit to BSNL GSM Exchange, Bhavani Peth and Karvenagar, third year students visit to Magna Flux Private Limited, Pirangut Pune and other industries.

Our placements have marginally raised to 69 and efforts for placement of others are still on. This year 23 students were deputed for internship programs in nearby industries. Thanks to the Alumini and Industry advisory board committee members for their kind help.

Department has organised various guest lectures for students to give insight on applications of various courses in curriculum. Mr. Pravin Hore talked about "How to write Java Applet program", Mr. G. S. Mani on "Applications of Soft Computing" also he made aware students about IEEE activities, Mr. V.V.Bang on "Business Case Studies the Lessons for Engineers" and Mr. Arvind Shaligram "Ultra-wideband Fiber Optic Communication Systems".

First time in history of the department, more than 75 students appeared for the GATE examination. Since this exam is useful in M.Tech., Ph.D. admissions and now made compulsory by public and few private sector companies for placements, I wish that 100 % of our B.E. 2017-18 batch will appear for GATE exams and will get qualified. I extend complete support for these students.

I wish you all the best for coming Academic year 2017-18. Let this year bring a grand success in your academic carrier.

Good Evening sir. I am Vivek Sharan, recently passed out of 2016 batch. Recently I have cleared the Air Force Pilot exam AFCAT & along with that I am also preparing for GATE-2017. Today after 2-3 years I studied SIGNALS & SYSTEMS, taught by a lecturer of a coaching institute. I am very much happy to say that even after 2-3 years all the concepts that

ndyou (Prof. M. S. Patil) had taught me in 2 year are still sharp & clear. It doesn’t appear for a moment that I have lost the touch of the subject. Let it be Laplace, Fourier, Z transform or any other formulae. Thanks a lot sir. Its one of the best subject I have ever studied and it was taught by one of the best faculty. Once again thanks a lot sir.

Get a Motivation for GATEI am going to tell you something about GATE. I know you must be aware of all the aspects and fruits of GATE but the feeling of scoring and getting an AIR is more than just a cherry on a cake! I am not a good scorer of GATE, to tell you about the extreme sweet fruits of GATE, but yes, I have experienced the feelings with my buddies. The benefits of GATE include some of these: (1) The dream of getting into top institutions of the Nation (some universities abroad accept GATE scores too.) (2) The monetary benefits include a monthly stipend of Rs.12,400/- which you get even if you are admitted to a private institute provided you have

qualified the exam. (3) Direct interviews/ offers in top PSU's provided you are in the top scoring list. (4) The act of getting another feather to your hat (The Master's degree). (5) You can even opt for an Integrated M.Tech-Ph.D (to add the third feather to your hat). To get a good score, hard work, patience and dedication is required. Start preparing from the very moment when you have heard about GATE. Keep away from social media as far as possible. I am not asking you all to quit Social Networking but they are definitely addictive. I believe all of you have seen your seniors posting photos and posts of moving out of India for higher studies but beware, they can be deceptive too. Not everyone gets a good university even if you have a good GRE/TOEFL/IELTS/GMAT score. If you can prove yourself technically in India, I bet it is possible for you to be anywhere in the world in near future. So take the step, open the GATE of your life!

Abhijeet Pise (M.E. Alumini)

Parent When I was in the process of engineering admission for my son Advait, I had an opportunity to visit the institute and talk to Head of Department. He took me around and showed me all the Labs and facilities in the department. I also had an opportunity to interact with faculty members and could see their enthusiasm. I could also see that efforts are taken to inculcate research culture amongst the faculty and the students. So I was convinced that it would be a correct decision to admit my son in VIIT. In the last 2 years, I could see the importance given to academics and the discipline maintained. At the same time, many avenues are made

available to the students to participate in co-curricular and extracurricular activities. This helps in overall personality development of the student. Now that the Institute is becoming autonomous, there is ample opportunity to inculcate best practices and to design and implement state of the art curriculum. My best wishes... Mr. Milind Patwardhan

Ltd.,JambhekarAutomations,Aeron System Sunay Enterprise, Crystal Peripherals & Systems Pvt. Ltd. Off campus placement and internship is co-ordinated by Mr. Vishal Ambhore and Mr. Piyush Mathurkar.

UL Automation Systems Pvt. Ltd. Is a well known company for manufacturing of electronic modules and circuits including relay interface module, passive interface module, panel accessories modules, PLC/DCS specific interface modules, CNC specific interface modules, customized cable harness and PCB assembly. We as interns learnt a lot beyond the scope of academic curriculum which one can learn only by getting into an industry. From buying components from market to transforming them into final product, they gave us flavour of each and every step. It had not much to do with the syllabus but basic knowledge of electronics was must to understand the process. We started with quality department were each component

required in industry was checked for eg. all the inductors were tested with DMM for their specified values. Once checked for their quality the components were sent to stores. In stores department where we were taught -how bill of material(BOM) is generated and how to use SAP -to manage the components buyied from the market -to release the work order from stores we along with components moved to PCB department where we placed and soldered the components onto PCBs. We also saw how wave soldering is done. We, on individual basis soldered more than 200 PCBs per day. There was a complete assembly, where components were provided from one end and assembled PCBs were produced by the assembly. After making PCBs the next was testing where all the PCBs were tested both visually and electronically. TESTED OK, finally we went to packing department where PCBs were packed as per the work order. The whole flow chart of “How an electronic industry works?” was revealed to us in very illustrative fashion. The fact that we had now idea of “working in industry” and “How an electronic industry works” made us feel good and gave us a lot of new experience.

Robocon is Asia’s largest robotic event, where many Engineering colleges participates in the event and represent their respective countries. At the National level, various engineering colleges compete with each other based on the theme given by the ‘ABU-ROBOCON’, every year. The winner of the national level event gets a chance to represent the country at international level. A team has to build a robot according to the theme set by the host country. Robocon 2017: This year (2017) the theme revolved around the Japanese concept called Asobi. The host country, i.e. Japan had

set a challenge of building a robot which would throw disc on the given 7 different platforms of different height and at different distance. Every team had to first knock off the ball placed on the platform and then land the disc. (Disc used was soft volley disc which was made using poly-urethane material due to which every disc had a different projectile.) Landing a disc on a single platform would score 1 point and placing such disc on all 7 platforms would secure a team Appare! which in Japanese means winner. A team had to complete the task in 3 minutes.Vishwakarma Institute of Information Technology [ V.I.I.T ] participates in robocon every year and has good

threputation in this event. This year our college secured 29 rank out of 130 colleges participating. We could not go further ahead in the competition but we can proudly say as it was announced in the event that, ‘This is perhaps the only college who has designed and build their own Printed circuit boards (PCB). Which is a very appreciable job, done by students at Second and Third year level’, whereas other colleges simply buy the boards. The overall performance was satisfactory. Here in robocon every member gets an exposure to many technical related stuffs, students get to learn and apply different practical knowledge, many different softwares for E&TC, MECHANICAL and COMPUTER students were covered under robocon. Knowledge other than technical related, such as team work, time management, soft skills, industrial exposure and many such things are also covered under robocon. Our college robocon team always tries to work hard every year with energy, enthusiasm

and a motto of ‘One Chance, One Dream, One Team’. All in all, it is a great experience!

traditionally experienced, interacting with two-dimensional interfaces for 2D experiences, such as using a smartphone or computer screen. The AI-driven internet will utilize 3D interfaces to generate 3D experiences. Your physical environment with become your internet interface. Take Uber for example, in which you interact with a digital service that takes into account your real-time environment and it creates a physical result by sending a car to your exact location. We will begin to see many more of these services emerge this year.AI, and machine learning in particular, is the process of building a scientific model after discovering knowledge from a data set. It is the complex computation process of automatic pattern recognition and intelligent decision making based on training sample data. AI techniques can replicate some specific elements of intellectual ability. The basic idea of AI is simple but its execution is complicated. First, the AI algorithm gathers facts about a situation through sensors or human input. The computer compares this information to stored data and decides what the information signifies. The computer runs through various possible actions and predicts which action will be most successful based on the collected information. The IT giants such as Google, Microsoft, Facebook, and others have all been using AI techniques in various research projects. Google acquired Deep Mind technologies who use neural networks and deep learning methods that deploy low-level transistor networks to produce high-level effectsIt was significant when Apple announced in June that it would open up Siri to third-party developers through an API, giving the wider world the ability to integrate Siri's voice commands into their apps. Similar decisions were made by Amazon, Facebook, Microsoft, and Google all of which have AI bots or assistants of their own. In 2017, we predict that there will be a new wave of artificial intelligence-based innovation, fuelled by the opening up of Siri, Alexa, Cortana, and other AI technologies. We expect to see coders using artificial intelligence as platforms to build new apps that can more rapidly expand AI uses and capabilities. We tend to think of IoT in terms of consumer products, but by far the biggest drive over the next year or two is likely to be industrial. Things like smart lighting are rolling out in increasing volume across cities, enabling energy savings from controlling lighting and maintenance savings from scheduling replacement bulbs as needed. These platforms are then sometimes providing information such as smart parking. Smart agriculture is taking off, especially in tracking and monitoring animals. Monitoring of remote assets from electricity meters to train tracks is also growing. These applications tend to lead because there's a clear business case for their deployment, normally predicated on cost-savings that can be delivered.2017 will see a fundamental shift in terms of industrial IoT adoption. As per 2016 global IoT survey, 38% of organizations have already started their IoT journey, and 57% are currently planning to, thus, making 2017 an inflection year for Industrial IoT adoption. 2017 will see a significant increase in investment in IoT by industrial organisations. Organizations are planning to increase their investment in IoT in the next one year.Governments will step in to mandate higher IoT security. High-profile DDoS attacks such as , which took down the likes of Twitter, Netflix, Spotify, and Play Station, helped to highlight the need for improved levels of security in IoT environments. As the number of connected devices ramps up, we will see not only more cyber criminals attracted to IoT, but also more sophisticated types of attacks. As IoT continues to expand beyond businesses and into the realm of smart cities and connected government programs, the requirement for watertight security will continue to rise. 2017 will be the year where we see policy makers and governments step in to mandate IoT security guidelines across industries. The SMART CITY initiative taken up by the new government will help in creating basic infrastructure for IoT implementation city wide. The number of devices able to connect to the internet and independently share information will keep growing, and more companies will look into launching integrated solutions with hardware and services. This trend may signal new interest in the deployment of IPv6. This could result in more connected devices and shift IPv4 addresses for human uses (like access to content that is still primarily hosted on IPv4-only networks). However, this growing number of connected devices will also come with new security concerns. Expect to see many players offering security for these new devices, and many conversations around the content being shared and how to promote privacy across the board. Security will remain a critical attribute for choosing the right IoT platform. Organizations are very aware of security concerns that come with IoT and will invest in solutions that offer robust security measures for devices and cloud data.

those in late October

Looking at the current technical advancements we will be witnessing a major change in history of

mankind. We are advancing with a great speed and targeted efforts. While IOT is connecting all the

dots and communicating smartly within them, Bigdata tools are helping us to understand the patterns

more accurately. There is a big distinction between artificial intelligence (AI) and artificial general

intelligence (AGI). AIuses your GPS to find the best route to the airport, with the AGI being

associated with actual intelligent thought, which ties into robotics. As we rely on artificial

intelligence to handle more tasks and both these categories evolve, we're going to see a huge demand

in 2017 for security skills applied to AGI, AI, and robotics. We are beginning to enter the initial stages

of consumer use of the "AI-driven internet." This new era of internet is a shift from what we have Mr.G.H.Chavhan

management authority might wish to monitor communications for purposes such as detection of non-licensed

transmitters. Currently smart modems, working on Software Define Radio (SDR) techniques, which adapts

the modulation techniques to achieve the highest possible throughput or data rate which can be supported in the

existing environment.

One of the essential step for doing this is to recognize or classify the modulation format of the intercepted

signal, which is the signature of a transmitter. Such demands also arise in many other civilian and military

applications such as surveillance, signal confirmation, verification, interference identification, electronic

warfare, threat analysis, and so on.

Automatic Modulation Recognition (AMR) is an intermediate step between signal detection and

demodulation. Originally, the analysis of modulation formats was performed manually; manual modulation

classification requires experienced analyzers and cannot guarantee reliable classification results. To solve this

problem, the signal processing community has conducted deep research in the ARM in the past decades.

In many cases, the AMR problems are blind in nature. That is, the signals captured by an AMR receiver may be

either digital communication signals or analog communication signals. Therefore, AMR algorithms capable of

handling both analog communication signals and digital communication signals are required in blind

environments.

The classification methods can also be categorized into two general classes: decision theory based approaches

(DTBAs), and feature matching based approaches(FMBAs). The classification decision is made by

comparing the likelihood functions or comparing the likelihood ratio with a threshold. The solution offered by

a DTBA algorithm is optimal in the sense that it minimizes the probability of misclassifications. However,

such optimal solutions generally suffer from heavy computational complexity. On the other hand, an FMBA

algorithm employs one or several features extracted from the received signal to make decisions. These

employed features are generally chosen in an ad-hoc way. Even though the FMBAs may not be optimal, they

are generally simple to implement, with near-optimal performance, when designed properly.

Algorithms for analog signals since it is difficult to assume a proper probability distribution function (PDF) for

the modulating signal (i.e., the information-bearing signal), the classification of analog communication

signals is generally based on some selected features derived from the received signals. e.g. The algorithms

used for classification of analog signals uses the analytic expressions of the ratio of the variance of the

instantaneous amplitude (IA) to the square of the mean value of IA .

A general assumption with digital communication signals is that the PDF of the symbols of each modulation

type is known in advance. In fact, it is often assumed that the transmitted symbols are independent identically

distributed (i.i.d.) with equal probability. This makes not only FMBAs but also DTBAs are applicable to the

modulation classification.

AMR systems are used in mobile and data communication for dynamic modulation selection based on the

operating environment and noise conditions, which will guarantee the higher data speed and throughput.

In traditional communications systems, transmitter and receiver work cooperatively.

That is, the receiver has a priori knowledge of the modulation format of the transmitted

signal. This include modulation type, nominal carrier frequency, modulation index, etc

for analog communication and modulation type, symbol constellation, alphabet size,

nominal carrier frequency, symbol rate, pulse-shaping function, frequency deviation and

so on for a digital communication system. The conventional communication studies

generally focus on making communications systems more reliable, higher power and/or

bandwidth efficient, and more secure. One of the fundamental requirements for a

communication system is the security. In contrast to this, the communication Mr. M. S. PatilAssistant Professor

The IEEE Students Awareness Seminar on 20th January 2017. Guest Speaker Mr. G. S. Mani

In the year 2016-17, data acquisition system for a UV-Visible-IR monochromator has been developed by two groups of students guided by Prof. R. S. Talware. This project is funded by ISRO-UoP Space Technology Cell. Prof. C. S. Garde is the principal investigator, Prof. S. S. Prabhu of TIFR, Mumbai is a co-investigator and Mr. Ravi Kesharwani is Research Assistant. Two linear CMOS array light detectors with 1x2048 pixels are used to collect spectrum from two reflection gratings. Gratings with 2400 grooves/mm and 1200 grooves/mm are used to generate spectra from 200 to500nm and 400 to 1000nm, respectively. The analog signal from CMOS arrays is fed to an AFE which converts analog to digital data using a 16 bit ADC. A clock from Nexus 4 FPGA initiates data transfer to FPGA through the AFE. Data is transferred from FPGA to PC through USB v2.0 using a FTDI chip. The spectrum obtained for the two wavelengths is collated into one spectrum. Both wavelength and intensity calibration is carried out by comparing the data from our system with that of a commercial monochromator. The monochromator is compact (17x17x8cm), robust with no moving parts.

thParent Meet for AY 2016-17 (semester: II) was conducted on 26 January 2017. A Total of 59 parents of SE, TE, BE wards were present. After attending the meeting at college level addressed by the Principal, parents came to the department. Prof Y. H. Dandwate HOD (E& TC), spoke to them on the many academic views of the

th stdepartment. He discussed them with autonomy visit on 30 and 31 January 2017, department’s vision, mission and various activities carried out by the department for overall development of a student. He stressed the importance of attendance, regularity and a parent’s role in this. After this parents interacted with class teachers and batch guardians on various issues. It was a successful event for the department.
