ADCTest Toolbox for MATLAB

Tamás Virosztek, István Kollár

Abstract

The IEEE standards for ADC and Digitizing waveform recorder testing (IEEE 1241, IEEE 1057) define the main characteristics of the testing procedures, but cannot determine every detail of them. Implementation of the procedures needs extensive programming and testing of the programs. Moreover, iterative methods need settings of the convergence criteria, maximum number of iterations, etc. Finally, the standards define least squares (LS) fitting, but do not deal with more advanced (however slower) maximum likelihood (ML) methods. Therefore, there is a need for software which is readily available, gives reproducible results, is numerically robust, has a graphical user interface, and can compare LS and ML fits. Many engineers and researchers use MATLAB in their work, therefore we decided to develop a tool according to the above requirements. It is available on the web as http://www.mit.bme.hu/projects/adctest/.
