Abstract

A phase equalizer in the receiver portion of a bi-directional communication system is disclosed equalizer for reducing precursor intersymbol interference without any substantial degradation in signal to noise ratio. The phase equalizer is implemented as a switched capacitor filter having a clock (switch) rate at least four times the data baud rate and a z-transfer function T(z) of a form: ##EQU1## wherein G, A, and B are fixed but adjustable coefficients.
