Transversal filter having parallel inputs

摘要

A transversal filter with an analog shift register has a plurality of parallel inputs and a serial output at which a filtered signal appears. An object is to provide as simple as possible a realization of the n signal evaluators allocated to the n stages of the shift register. This is achieved by providing the n signal evaluators in a signal path proceeding from the input of the first stage over all n stages, and to evaluate according to evaluation factors bn through b1 which occur in the system function H(z)=box(1+b1z(1+b2xz( . . . 1+bnxz))) describing the filtered signal, where z is the delay which the signal values respectively experience when traversing a stage of the shift register. The filter is employed as an analog filter in communication technology.
