Is MUX working for PCM signal?

May I know that is MUX working also for PCM signal? From the ArduPilot project I know that it works totally fine with PPM signal.Any experience and suggestions are greatly welcome.Many thanks in advance.

  • yes, since the ardupilot board uses the signals from a receiver which are PWMs sent to servos.
    Had there been a 1 wire reading of data(all the channels muxed into 1) from the receiver then PPM or PCM case is to be considered.
    Whreas in ardupilot individual PWMs(individual channels) are read.

    I worked on the Futaba FM Tx/Rx and used single wire to read data...
    The advantage is that u dont have to read each and every channel from receiver to get the full Transmitted data....
    U simply read the pulses appearing on a muxed channel
    U wait for a very long pulse generally a flag(meaning start of frame or start of following data)
    U then read individual pulses and keep storing them in, say an array.

    I stored them in an array of size 6 since i was using 6 channel Tx.

    Simple as it is.

    PCM and PPM are only meaningful within the Rx. At the servo level, which is what the MUX works at, it's all PWM. So yes.
