Correlation methods are widely used in different branches of science and engineering, particularly in radio electronics, automatic systems, and control and measuring technology. In measuring problems, which are based on the use of the correlation method, the correlator is of primary interest. In this case we study primarily the systematic error in correlators of different types operating without interference and under conditions where the secondary units of the system amplifiers, filters, transducers, etc. do not introduce additional error. In examining systems for detecting and measuring the parameters of weak signals attention is focused on analyzing the potentials of the system for separating the useful signal in the presence of noise. Deviations from optimal design in the system which result from production technology are generally ignored.
