โœฆ Synopsis


We present a method for obtaining the time}frequency structure of a signal that has been "ltered. A simple procedure is given for obtaining the instantaneous frequency when the signal and "lter are asymptotic signals.

A computationall\_v eficient technique is developed for the design of twodimensional (2-D) recursive digital jilters that meet simultaneously magnitude and phase specifications. A quadrantal symmetry which exists in the 2-D frequency response is incorporated into the 2-D jilter design. The denominat
