Pulse Width Modulation is definitely the preferred method of dimming an LED with a microcontroller, but we were interested in hearing about a different method called Binary Code Modulation.

To receive the signal, the receiver must be able to follow the hop sequence of the transmitter ... For example, using pulse code modulation, pulses from different signals are interleaved in time, and ...

Pulse-Code Modulation The growth of communications traffic has enhanced the attractiveness of this method, which converts messages into binary digits that can then be transmitted in the form of ...
