In order to remove at least one of amplitude and delay distortions which tend to occur during signal transmission, the invention features circuitry wherein a received IF digital signal is fed through an equalizer circuit to a demodulator and wherein the demodulator outputs a series of data and error signals to a control signal generator. The control signal generator produces in-phase and quadrature control signals which are appropriately added and subtracted and subsequently averaged in an adder and subtracter circuit before being applied to a series of equalizers in the equalizer circuit.
