Title: Signal to noise enhancement of lock-in amplifiers
Authors: Neelakantan,K.

Citation: Review of Scientific Instruments,51 (2),251-252
Abstract: A lock-in amplifier can be considered to be a special case of the more general box-car averager. Expressions for the output noise voltage of lock-in amplifiers are deduced from the corresponding results derived earlier for box-car averagers. Deviations from the simple (4 RC) 1/2 law are shown to exist in the case of nonwhite noise.
