Abstract

PURPOSE:To prevent the erroneous signal error detection due to an exclusive signal used for detecting the signal error by applying time division to a received data, storing the result in plural storage means and comparing all the data to detect the signal error. CONSTITUTION:An output data (a) of a high-order circuit is supplied to latch circuits 1-3, and a data output signal (b) is given to a latch selecting circuit 4. Time division data (d), (f), (h) being outputs of the latch circuits 1-3 are supplied to a comparator circuit 5, which compares the time division date (d), (f), (h) and brings a data error detection signal (j) to a level '1' when they are all coincident, and brings it to a level '0' when they are dissident. Thus, the signal error can be detected without using any exclusive signal, and the occurrence of erroneous signal error detection due to the unexpected erroneous change of the exclusive signal itself used for detecting the signal error is prevented.
