Abstract :
This article presents an alternative method for testing Analog-to-Digital Converters (ADC) by non-coherent spectral analysis using weighting windows and focusing on the maxima of the window spectrum instead of summing the power inside the main lobe of the window spectrum, as it is always done. Comparing to the existing method, theoretical laws for computing fundamental, harmonics and noise power spectral densities are derived and software simulations are used to validate them.
