摘要：
An approximation of the Wigner distribution of a filtered signal is presented. The approximation is simple to apply, yet insightful, in that it shows the effects of the magnitude and phase of the frequency response of the filter on the Wigner distribution of the signal. Also given is an approximation for the Wigner distribution of an amplitude modulated signal. Examples are given to illustrate the approach, including application of the approximation to wave propagation.
