ABSTRACT:
A transversal type automatic equalizer includes circuits for differentiating the equalized signal, sampling the equalized signal under the control of a timing signal, and generating an error signal from the sampled signal. The differentiated and error signals are multiplied together and a variable phase shifter phase shifts the timing signal in response to their product to provide optimum equalization.
