ｂの送信を誤って受信することは無くなる。When the carrier frequency of the infrared remote controller 1 to the control transmitter is set to fa using the selector switch 5, the corresponding infrared remote control receiver is also set to the selector switch 15.
The narrowband filter 14a is set to pass only the frequency [a]. Even if the receiver receives a signal with a carrier frequency fb, the narrow band filter 14a does not pass signals other than frequencies fa, so the receiver receives a signal with a carrier frequency fb.
This eliminates the possibility of receiving the transmission of b by mistake.
