ABSTRACT:
A transversal filter has an analog shift register exhibiting a series input and a plurality of parallel outputs which are connected to a summing and/or subtracting circuit. A simple realization of signal weighting circuits assigned to the stages of the shift register is achieved in that n signal weighting devices assigned to a group of n stages are disposed in a signal path which extends from the input of the first stage of the group over all stages thereof and in that the signal weighting devices of the n stages respectively weight according to filter coefficients b.sub.1 -b.sub.n which occur in the system function
