E. Sisinni – Digital Systems for Signal Processing

TeamsTeams

• Individual and team (with 2 members in each group) activities are allowed.

• Each “group” will be provided with a DSP/FPGA board. You can use your personal computer or a Lab machine to manipulate the boards, as long as the required software is installed.

• Following is the grading criteria with a total of 10 points for any projects. But different projects may carry different weights in your final grade.

– Project report: 30% – Original contribution: 10%– Oral discussion: 60%

• Typically, all members in a team will get the same grade for a project, unless the team leader or other members report that someone contributes little to the project and he/she should get only a certain percentage (e.g., 90%) of the team’s grade.
