Abstract
Incoming data pulses from a transmission channel are differentially combined with weighted data pulses from preceding cycles to form an updating signal fed in parallel to a multiplicity of weighting circuits for digital multiplication with respective coefficients K.sub.1 - K.sub.N, the output signals from these weighting circuits being synthesized in staggered relationship to form a composite signal fed to a quantizing decoder. The weighting coefficients K.sub.1 - K.sub.N are continuously modified under the control of an error signal derived from a locally generated reference code during an acquisition phase and from the decoder output during an operating phase.
