RC PPM signal

RC Receiver Overview

A standard RC receiver is made of four main blocks :

  • Radio-frequency block (FM receiver + antenna) which converts through demodulation the signal into a form usable for the other blocks. This particular signal is a PPM (Pulse Position Modulation) coded signal.
  • PPM signal decoder which converts the pulse positions into PWM (Pulse Width Modulation) servo signals
  • Synchro blank detector block which detects PPM frames separation in order to re-initialize the PPM decoder.
  • Power supply block which supplies all blocks from external receiver supply (on one of the servo header)
