ABSTRACT:
A signal processing device wherein an incoming one-bit digital audio signal is blocked by every predetermined bit-length block. Two consecutive blocked frames are compared and it is judged whether or not an integral value of each frame is a predetermined value. If a portion where coincidence between the frames and coincidence of the integral value continue for a predetermined period of time, mute processing is performed.
