1. ADC test library in C Ján Šaliga Dept. of Electronics and Telecommunications Technical University of Kosice, Slovakia

2. Agenda Introduction System of function Application example: PC sound card test

3. 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

4. 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: J. Šaliga, S. Csernok: C-language function class for signal processing at ADC testing, proc. of ADDA & EWADC 2002 conf., Prague, pp. 235 - 238 Access in the present: jan.saliga@tuke.sk or http://meas-lab.tuke.skjan.saliga@tuke.sk
