Abstract

A circuit for compensating for the varying amplitude, frequency and/or phase characterictics of the signal source pulses during operation. In the preferred embodiment the circuit includes a tapped delay line (20) to which received signal samples are supplied, the delayed output from each of the taps being weighted in accordance with a suitable weight generator circuit (24) and the weighted signals being appropriately summed to supply an output signal to the receiver.
