A programmable binary correlator with one-digit, digital sampling is disclosed. The binary correlator includes input comparators for converting a signal to digital form, each comparator connected to a storage unit. The storage units are connected to programmable counters which, in turn, coact, through a control element, with additional counters. The various counters, control element and storage units cooperate with a unit for supplying programmed signals. A clock signal generator is present to control the correlator timing and supply necessary pulse signals. By storing digital representations of two input signals in the storage units in a particular way, by comparing these stored signals bit by bit in a coincidence tester, by repeating the comparison by repeatedly shifting one stored signal relative to the other, and by storing the number of coincidences in a final counter, a correlation of the two input signals is made. An analog correlator employing a plurality of such binary correlators is also disclosed.
