ABSTRACT:
A signal processing apparatus includes a deemphasis processor, which is arranged to receive a signal which has been emphasis-processed on the basis of a predetermined emphasis characteristic, to separate only a signal of a predetermined frequency band from the received signal, to effect deemphasis-processing of the separated signal on the basis of a deemphasis characteristic corresponding to said emphasis characteristic and then to effect phase-compensation of the signal, thereby restoring an original signal corresponding to the received signal. This apparatus enables stable restoring processing, without being subjected to adverse influence by a noise component.
