Abstract
A noise eliminating signal compensation circuit in an audio device such as a car radio is configured to produce a compensation signal having the same frequency and level as those of an entered signal for signal compensation during noise removal, so as never to degrade its signal compensation capacity during noise removal when the switching time for noise removal is relatively long with respect to the wavelength of the entered signal.
