ABSTRACT:
An automatic equalizer has a circuit for sensing cable effects that generates a control signal for a variable equalizer. A digital signal from a transmission channel is input to the variable equalizer to produce an equalized digital signal as a function of the control signal. The equalized digital signal is input to the sensing circuit which detects over-shoot or under-shoot of transitions in the equalized digital signal and adjusts the control signal accordingly to produce a balance in the transitions.
