A small computer inside of the receiver takes these pulses of electricity and turns them into an audio signal. This audio signal is then amplified and sent to the headphones themselves, which play the sound. For the receiver side, a photodiode D1 feeds high gain IR remote control preamp IC, a CA3237E. U2 is a PLL FM detector tuned to around 100 ...

It outputs from its DOUT pin a binary sequence containing an address, coming from inputs A1–A5, and data reflecting the state of inputs D6–D9. The addresses are used here for the ‘house’ code, while data lines D7,D8,D9 code the transmitter number from 0–7. Line D6 transmits the battery status, measured by comparator IC2.
