Abstract
An automatic transversal equalizer is provided wherein the input signal is sampled and stored on a series of capacitors. The capacitor voltages are sequentially recalled for application to an analog multiplier which also receives a sequence of coefficient voltages which have been stored by a second series of capacitors. The single analog multiplier performs the functions of the plural voltage controlled attenuators of prior art equalizers.
