A digital correlator using delta modulation

Correlators are powerful instruments for analyzing signals. Recently many digital correlators have been developed. Their main parts are delays, a multiplier, and an integrator, the basic principles being the same in most cases. In this paper, the author proposes a new method (the M.I. Unit) which provides a multiplication and an integration all in one circuit by using delta modulation. Due to using this method, it is suggested that simpler digital correlators can be constructed.
