Abstract
A signal detector circuit comprises a plurality of series-connected data latch circuits. An input signal and clock signals are applied to the first data latch circuit, the clock signals being effective to shift the input signal along the succeeding data latch circuits. The outputs of the data latch circuits are coupled to the plural inputs of a plurality of first logic circuits in a manner such that the outputs of different data latch circuits are combined at different ones of the first logic circuits. The outputs of the first logic circuits are combined in a second logic circuit which produces an output signal. The input signal may be a composite television synchronizing signal and the output signal may correspond to the vertical sync pluses in the composite synchronizing signal.
