ABSTRACT:
A signal processor is arranged such that, after an input signal is converted in such a manner that a first high-frequency component is relatively attenuated more than a low-frequency component by a predetermined amount as compared with a state before the input of the signal, a second high-frequency component which is different from the first high-frequency component is amplified, thereby reducing a noise component without exerting an adverse effect on the signal.
