Claims (1)

[Claims for Utility Model Registration] A pulse generator that sends out a pulse train; a memory that stores predetermined data in advance and sequentially sends out the data in response to the pulse train supplied from the pulse generator; a signal generator that generates a frequency-modulated signal based on the signal from the memory; a transmitter that emits the frequency-modulated signal; and a receiver that receives the frequency-modulated signal. A shift register that stores the output signal from the receiver and outputs the signal to be stored at its plurality of output terminals, and a frequency-modulated signal similar to the above-mentioned frequency-modulated signal to the output terminal of the shift register. a reference signal generator that outputs to a plurality of corresponding output terminals, a signal that is sent to a plurality of output terminals of the shift register, and a plurality of output terminals of the reference signal generator that correspond to the output terminals of the shift register. 1. A transmitting/receiving device characterized by comprising an adder that mutually adds the transmitted signals and further adds the values obtained for each output terminal to each other.
