Wigner cross-terms in sampled and other periodic signals

Rhodes, William T. ; Healy, John J. ; Sheridan, John T. (Optical Society of America, 2009-10-11)

If we sample a scalar wave field, it becomes periodic in frequency. We examine the cross-terms which occur between these periodic replicas in the Wigner-Ville distribution function of such a signal. We present analytic ...
