PURPOSE:To operate with only 2 fitted D-type FF circuits of a simple constitution, in a receiving circuit using an IC which is capable of processing a multichannel and having decoded its output, and also controls turn-on and turn-off of an apparatus to be controlled, by transmitting and receiving the information having the same contents. CONSTITUTION:A demodulated pulse train signal from an antenna is amplified 2, and is provided to, for instance, a pin (13) of an IC11 of a discriminating circuit 3 for discriminating the contents (information) of this signal, and one input terminal of a NOR gate 12 which has been provided for setting an operation of the IC11. After a prescribed time, a pulse having a prescribed width is generated in order as an output of the IC11, is provided to a corresponding pin of an IC15 of the circuit 3, and decoding outputs O1-O5 are outputted in order from the IC15. Subsequently, for instance, the output O2 which has been fixed to a high level is provided to an input terminal D1 of a D type FF16, and after a constant time, its output Q1 becomes a high level, the output Q1 becomes one pulse, is provided to a D type FF19 which forms a holding means of the next stage, and an apparatus 7 to be controlled is controlled by use of its output Q2. |
