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.
