Multichannel wireless remote control circuits F36-F and F36-J

Published:2011/5/12 7:24:00 Author:TaoXi | Keyword: Multichannel, wireless remote control

This circuit uses the multichannel wireless remote control circuit which is composed of the F36-F and F36-J. In the transmission circuit, we use the DTMF coding & decoding circuit to change the launch button input signal into the 4-bit binary code and then input this signal to the F36-F to send out. In the receiving circuit, the F36-J receives the remote control signal and changes this signal into the 4-bit binary code, then changes this 4-bit binary code into the channel control signal through a four-sixteen line decoder to control the corresponding circuit.
