A digital m of n correlation device using signal and reference shaft registers, modulo 2 adders, unique 1-bit DA converters, and single resistor analog summing provides a very fast correlation product for pulse compression modulations such as phase or frequency shift keying. The compression ratio for the digital m of n correlation device according to the present invention is 1681 equal to the number of bits. The device is capable of bit rates in excess of 100 Mbs and is well suited for LSI fabrication.
