A system for digital signal processing, including a random access memory (RAM) accessed by counters and used for storing and shifting signals in a convolver, correlator, matched filter or multiplier. An input signal and a reference signal are applied from opposite ends of the device such that the signals scan past each other at a relative velocity with respect to each other for obtaining either the convolution or correlation function of signals. The RAM operates as a shift register delay line and provides time scale inversion of signals when desired.
