Abstract
An equalizer for partial response signals is described which is constituted by a shift register and an analog adder, from the output of which a corrected signal is produced. Two of the switching stages forming the shift register have their outputs connected to inputs of an additional analog adder, and one of these shift register stage outputs is connected to the analog adder over an adjustable amplifier. The output of the additional analog adder is connected to a correlator, the value of the output signal of which controls the gain of the adjustable amplifier.
