- Abstract:
- In the last several years, many high-resolution and high-speed ADCs have appeared on the market. Since the signal purity of commercial generators particularly at MHz frequencies has not essentially increased in the same period, the problem of how to test ADCs has rose. This fact initiated the research of alternative methods based on either the application of special signals or posteriori correction of the measured sine-wave signal. The latter method concerning a simple correction in the frequency domain was analyzed, extended and practically applied. The application and the results of this extended method at the frequency of 1 MHz are presented in this paper.
