Introduction

Existing software: end user application: LabVIEW

J. Blair: “Sine-fitting software for IEEE Standards 1057 and 1241” IMTC’99. Proceeding, Venice, Italy, May 1999. pp. 1504-6.

Matlab J. Márkus, I. Kollár: “Standard framework for IEEE-Std-

1241 in Matlab”, IMTC’01 Proceeding, Budapest, Hungary, May 2001, , pp. 1847 – 1852

J. Márkus, “ADC Test Data Evaluation Program for Matlab” http://www.mit.bme.hu/services/ieee/ADC-test

Why such a library? Open source library was missing C language: very common, simply transferable on

other platforms and languages Developing tool: LabWindows/CVI by NI in form of

Instrument driver Based on DYNAD, useable for IEEE, added special

functions Introduced:
