Certain Digital Quadrature Signal Processing Techniques for Bandlimited Signals.
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)
