Pulse Code Modulation (PCM) is the simplest form of waveform coding. Waveform coding is used to encode analogue signals (for example speech) into a digital signal.

Pulse code modulation (PCM) is being explored as a possible technique for greatly increasing the information handling capacity of conventional telephone cables. For example, there is a possibility ...

PWM was one choice, and some example code uses a timer to do PDM. However, that is not very efficient. The other alternative is to use the I2S output. However, this does require a few workarounds.

Those following the ProtoStack tutorials will be happy to hear that there is a new installment which explains Pulse Width Modulation. If you’ve never heard of PWM before, it’s a method … ...

A North American telephony standard for converting analog voice into a digital data stream using pulse code modulation (PCM). The "pulse code" in PCM comes from the telephone company's method of ...

Abstract: We propose a digital-cascaded-pulse-code-modulation radio-over-fiber (DCP-RoF) scheme and verify it experimentally in a coherent transmission system. The 50-Gbaud 2-order 6-bit DCP-RoF ...
