Abstract

PURPOSE: To prevent the decoding of the output signal to the erroneous position as well as the error of the double output by connecting both the odd-even decision circuit and the encoder circuit to the output of the decoder and then comparing the encoded signal with the input signal of the decoder.
CONSTITUTION: The binary data to be decoded is applied to input terminals A, B and C of decoder 100 as well as to comparator circuit 103 via signal line 201 to detect the agreement or disagreement of the signals. Then output signals 210 ∼ 217 of decoder 100 are applied to odd-even check circuit 101 via signal line 205 as well as to encoder circuit 102 via signal line 206 to give the binary encoding to the input signal. After this, output signal 218 is applied to circuit 103. And if an agreement is secured, output signal 208 of circuit 103 is turned to logic "1" and accordingly output signal 207 of circuit 101 is also turned to logic "1" with output signal 209 of NAND circuit 104 connected to circuit 101 turned to logic "0" respectively, thus the normal state being indicated.
