Abstract:
The patent relates to an analog feedback circuit for producing a null or zero output for two either in-phase or 180 degree out-or-phase input signals applied to the circuit. The dc control voltage is applied along with the first input signal to a multiplier whose output is summed with the second input signal in an operational amplifier to provide the amplitude and phase of the control voltage.
