Abstract
Disclosed is a system for detecting non-coincidence of codes having a means for comparing an input coded signal and a predetermined coded signal to generate a non-coincidence signal including correct and error bits; a means for counting a number of the error bits included in the non-coincidence signal, thereby generating an error bit count signal for indicating the number of the error bits; and means for detecting non-coincidence between the coded signal and the predetermined coded signal by checking that the number of the error bits indicated by the error bit count signal is greater or equal to a predetermined error number.
