Abstract
An all rate equalizer provides direct equalization of a data signal which is automatically adjusted based on data rate and transmission line. The equalizer is embodied in a closed loop circuit in which the amplitude of the data signal is the controlled parameter. The DC amplitude of the data signal is restored by an adjustable gain circuit and the bandwidth of the data signal is restored by an adjustable frequency circuit. The signal processing circuits are adjusted by a control processor in accordance with pre-determined tables of control signals corresponding to frequency and gain values required to provide equalization of the data signal for virtually any given data rate and transmission line. The all rate equalizer thereby automatically provides equalization of the data signal that is optimized for any combination of data rate and transmission.
