The same as digital coding circuit, encode outputted by code hopping encoding circuit can be transmitted by infrared ray or radio wave. At the receiving end, modulation signal received by receiving circuit, demodulation circuit is amplified and demodulated, then the code hopping decode chip outputs analyzed channel data, to control relevant circuit by executing circuit. Infrared remote control circuit shown in the figure consists of code hopping chip TR1300/1315 and infrared remote control receiving module PIC12043. remote control receiving circuit: infrared receiving demodlation decode and output circuit:
