Abstract
Incoming data pulses from a transmission channel are differentially combined with feedback pulses from the downstream end of a cascade of (N-1) delay networks to form an updating signal fed in parallel to a first set of multipliers for weighting with respective coefficients b.sub.1 - b.sub.N.sub.-1. These multipliers deliver optimized signal components to the inputs of respective delay networks of the cascade, through the intermediary of adders in each instance except for the first delay network at the upstream end; a further adder downstream of the last delay network may superimpose the updating signal, weighted with a coefficient b.sub.N by an N.sup.th multiplier of the first set, upon the feedback pulse issuing from the last delay network to generate an additional signal component. At least the more significant signal components, from the inputs of the delay networks located further upstream in the cascade, are weighted in a second set of multipliers with respective coefficients a.sub.1, a.sub.2 etc. before being additively combined, in a summing circuit, into a composite output signal.
