Abstract
A dial pulse receiver having a clock pulse input to a counter and a first and second flip-flop. The outputs of the two flip-flops are coupled to an exclusive OR gate to reset the counter. The counter output and the two outputs of the second flip-flop are coupled to an output gate and latch configuration. The counter is set to enable the latches so only a legitimate dial pulse is recorded.
