Abstract

A signal processing system for measuring the amplitude and time delay responses of a network over the bandwidth allocated to the network wherein a plurality of subburst signals each in the form of a suppressed-carrier, amplitude-modulated signal, is applied to the network. The signals received from the network are provided in complex form having in-phase and quadrature components. Matched filters respond to such components and the matched filter outputs are processed so as to determine the estimated amplitude and time delay responses of the network at the carrier frequency of the subburst signals over the operating bandwidth of the network.
