ABSTRACT:
The phase shift imparted to a signal is accurately controlled by passing the signal through a phase shifter in which the phase shift is adjusted by an automatic feedback control circuit. The control circuit senses the actual phase through the phase shifter and combines this information with a signal representing the desired phase to generate a control signal for the phase shifter.
