Alternative Method of A/D Conversion Quality Verification

Popis výsledku v původním jazyce

Well known methods for testing ADC dynamic quality require low-distortion generator and it can be a problem by testing high-resolution ADCs, same as middle resolution high-speed ADCs. The paper describes new alternative method - Spectrum Correction Test.It is based on the FFT test, but the distortion of a testing signal is corrected. The basic idea is the fact, that the Fourier Transform is a linear operation. Therefore it is possible to recognize spectral lines, which belong to the generator used and the lines of the ADC. The spectrum measured on the ADC's output can be corrected for the known spectrum of the generator. A PC simulation was executed to investigate, if this method could be used. Than the system for evaluation of the test was designed and realised. The first experience and achieved results are also published in this paper.
