ABSTRACT:
A noise limiter for a binary circuit in which a thin film superconductor is put in shunt between a transmission line and ground. The thin film exhibits a gradual transition region as a function of current between normal conduction and the completely superconductive state. The dimensions of the thin film are chosen such that a high level signal on the transmission line falls in the gradual transition region and the impedance of the shunt is greater than the characteristic impedance of the transmission line while a noise component on the low level signal falls in the superconductive region and therefore is reflected by the zero-impedance shunt.
