Windows for ADC dynamic testing via frequency-domain analysis

In this paper the frequency-domain dynamic test of analog-to-digital converters is considered under the assumption of non-coherent sinewave sampling. A procedure is described which is based on the windowed Discrete Fourier Transform, optimized for the achievement of high estimation accuracy. To this aim the class of windows belonging to the set of Discrete Prolate Spheroidal Sequences is adopted for the reduction of the effects of spectral leakage. Practical suggestions are finally given for a straightforward applicability of derived results and for an efficient estimation of ADC spectral parameters
