Abstract
A binary transversal filter which has a plurality of stages of shift registers that are driven by timing signals of a frequency which is a multiple of that of clock pulses being introduced, and a weighting circuit which weights outputs of shift registers of each of the stages, so that outputs of the weighting circuit can be synthesized. The characteristic feature of the present invention resides in the facts that NRZ signals are introduced into the shift registers, and the shift registers are driven by timing signals of a frequency which is a multiple of that of clock pulses of the NRZ signals.
