components rather than others to implement the AIC board for
the vector signal analyzer, namely an analog multiplier instead
of a mixer, to reduce the distortion phenomenon, or a Wavelet
signal, if the monitored frequency interval of the input signal
requires to be extended. On the other hand, the numerical
analysis suggests key aspects on the measurement matrix to be
adopted in the reconstruction phase, such as the importance
of including architectural non-idealities and actual features of
the prototype, first of all the pulse shape of signals involved in
modulation processes and the impulse/frequency response of
filters located ahead ADCs working at sub-Nyquist rates.
