DROP-OUT CORRECTION APPARATUS

A signal processing device detects information drop-out parts of an incoming information signal by dividing the information signal received for a given period of time into an n number (n: an integer which is at least 2) of blocks and by forming an information drop-out part signal indicating a part that has an information drop-out within each of the blocks. The device is thus arranged to be capable of promptly finding the parts of the information signal having information drop-outs.
