Abstract
A coincidence circuit for detecting when n-bit binary input data coincides with the current value of an n-bit counter. A plurality of '1' detecting circuits determine, when a corresponding input bit is one, whether a corresponding counter bit is also one. A first-coincidence detecting circuit determines the first time that all the '1' input bits have corresponding '1' clock bits. Each '1' detecting circuit includes an inverter and a NOR gate. The first-coincidence detecting circuit includes an OR gate and a latch circuit.
