Abstract
Correlation techniques are used to measure weak fluctuating signals encountered in various physical problems. A new correlation meter is proposed which operates using higher harmonics of a heterodyne signal. The sensitivity of the proposed device is evaluated, the measurement error caused by the first approximation is estimated, and the influence of nonlinear distortions of the analyzed signals is studied.
