Abstract:

The report discusses practical methods for signal processing bandpass signals by digital quadrature methods. These methods assume a sufficiently dense uniform sampling of a bandpass signal and include 1 extractions of quadrature samplings from uniform samplings, 2 polynomial interpolations in which the sampling frequencies f sub s pi W ensure exact interpolation, and 3 error corrections for interpolations over a finite data base. Also included are applications to the problems of measuring the instantaneous envelope, phase, and frequency of bandpass signals. Author
