Abstract : The patent describes a simple frequency latch for use as a logic circuit building block in which two or more signals of predetermined frequency are fed into narrow-band amplifiers and mixers. When all input signals are present, they are mixed together and the mixed signal is fed back to the inputs to shut off further input signals. The mixed signal is stored in the circuit by means of an oscillation loop.
