ABSTRACT:
A digital signal regenerator receives a four-level input signal, amplifies, reshapes, and retimes that signal into a regenerated four-level output signal. A wide range controlled equalizer amplifies and reshapes the four-level input signal into an intermediate signal. A variable all-pass circuit varies the shape of the equalizer's phase characteristic to optimally shape the four-level signal as a function of the maximum amplitude of the four-level input signal. The reshaped four-level signal is retimed and amplified into the regenerated four-level output signal. This enable multiplying the rate at which information is transmitted for a selected pulse rate in the transmission line.
