ABSTRACT:
A tapped delay line (39) terminated with its characteristic impedance at both ends is connected to receive a differential input signal across ends (35, 37) of the delay line. Delay line taps 41, 43), as well as ends, are connected symmetrically to a pair of summing networks (71, 73) where voltage signal components having different delays from the input signal are linearly combined. The output waveforms from both summing networks are combined to provide a balanced differential signal that has been both amplitude equalized and differentiated from the input signal with variable amplitude for use in a signal detector (87, 89) that requires such a shaped signal waveform.
