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) and delta modulation (DM) are two methods of converting analog signals into digital signals. Both methods are widely used in electronic engineering for communication ...

PDM — pulse density modulation — is similar to PWM and, like PWM, requires a filter that could range from a simple RC network to an active filter. You can see the result in the video below.

Simple Matlab App that calculates and displays the Delta Modulation. Delta modulation, also referred to as Δ-modulation or Δ-M, is used for pulse frequency modulation (PFM) and pulse density ...

TASBot's newest bit of game-breaking magic relies on the vagaries of the NES' DPCM (differential pulse code modulation) sound channel. This one-bit data stream was used to play extremely basic ...

However, pulse-code modulation of sound signals for distribution between broadcast centres has been used in different ways for several years. For video signals, development work carried out by ...

This paper describes the direct pulse code modulation (PCM) method of a gain-switched LD and its application to a high-speed electrooptical time division multiplexer. The method can effectively remove ...

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 … ...
