Quantization noise, linearity and spectral whitening in the LFAA quantizer

G. Comoretto, S.Chiarucci

INAF Osservatorio Astrofisico di Arcetri


The LFAA ADC must provide high dynamic range, high linearity, good performance in presence of RFI and low added noise. These specifications may be seriously degraded by the large variation in spectral power density across the input band. This aspect is discussed here, together with the advantages and disadvantages of a whitening equalization filter.
