Abstract
The carrier suppression circuit of the present invention is utilized to minimize electrical imbalances within double-balanced mixers. The circuit operates upon a modulating signal, having at least two states so as to adjust the dwell time that the signal stays in a particular state to counteract the effects of electrical imbalance within the mixer. Minimization of the electrical imbalance provides a greater suppression of the carrier signal which, in turn, improves the quality of the signal both at the transmitter and at the receiver.
