Abstract

PURPOSE:To simplify a circuit constitution in the receiving side by causing one of plural Hamming code data HCD and Fleming code data FCD to agree with each other. CONSTITUTION:The parallel output signal of shift register 2 is applied to HCD correcting circuit 6, and HCD is accurately corrected even for the error of one bit or less, and the signal is taken out. The output signal of circuit 6 is applied to NAND gate 7, and the pulse from terminal 8 and the pulse from the FF consisting of NAND gates 10 and 11 are operated for NAND, and FCD agreeing with HCD is detected. Consequently, circuit 6 is used commonly as a part of the FCD detecting circuit, and the receiving-side circuit can be cheap, and corrected data is always used by circuit 6, so that sure data transmission possible.
