A method for determining amplitude and phase errors of signal harmonic components caused by A/D converter quantization is presented. The method is realized by a computer algorithm which uses output probes of the converter as the input data. Performed simulation studies indicate that the method is correct. It is possible to precisely determine the harmonic parameter measurement errors caused by the quantization.
