Abstract :
Signal-to-noise enhancement is achieved by use of a time-variant superconductive filter. The photodielectric effect of a semiconductor within the high-Q superconductive cavity acts as the perturbing mechanism which allows the narrow-band cavity to track the instantaneous signal modulation.
