Abstract :
The correlation technique is applied experimentally to determine the power density spectra of the output of two non-linear devices, the linear and square-law rectifiers. Curves of the input and output autocorrelation functions obtained experimentally for inputs of filtered noise with and without a sine wave are compared with the theoretically calculated curves, and thus an experimental check on some known theoretical results is obtained.
