ABSTRACT:
The delay elements of a signal energy transmission network are divided into separate portions through which the transmitted energy is phase shifted by substantially equal amounts. A phase correction circuit reverses the phase shift through one of the divided delay portions by subtracting the delayed signal from the input signal of that portion to obtain a phase error signal, and then modulating the undelayed signal input to that portion with the phase error signal to reverse the phase shift caused by that same portion, so that the effect of the remaining delay portion on the phase is thereby cancelled in order to maintain a constant frequency vs. phase relationship.
