Abstract
An input coded signal is compared with a predetermined coded signal to generate a non-coincidence signal. Error bits of the non-coincidence signal are changed to correct bits by a predetermined number of bits. When the non-coincidence signal has no longer any error bits as a result of changing the error bits to the correct bits, the input coded signal is determined to be correct.
