Abstract:
1. A circuit-based apparatus for operating on an input data stream, comprising: at least one delay-line circuit configured and arrange to characterize the input data stream modified over time; a plurality of integrators configured and arranged to respond to the at least one delay-line circuit by providing a plurality of integrated signals; a plurality of weighting amplifiers configured and arranged to amplify the plurality of integrated signals by a plurality of respective time-varying weighting factors and thereby provide weighted signals; a signal-combining circuit configured and arranged to respond to the plurality of weighting amplifiers by combining the weighted signals; a plurality of parallel signal-processing circuit paths, each parallel signal-processing circuit path configured and arranged to couple the weighted signals, as weighted by one of the respective time-varying weighting factors, to the signal-combining circuit, whereby the signal-combining circuit is configured and arranged to provide a signal representative of the input data stream by combining the weighted signals provided by the parallel signal-processing circuit paths.
