Abstract

The digital recursive filter has three multiplier and a summation circuit (10). The first multiplier consists of two multiplying elements connected in parallel with that part of the store storing the instantaneous value of the sample. There are these multiplying elements in parallel withthat part of the store storing an earlier instantaneous value of the sample, and two multiplying elements in parallel with that part of the store storing an even earlier value. The second multiplier has corresponding multiplying elements.
