PCM Audio - COMPLETE GUIDE AND REFERENCE
https://planethifi.com/pcm-audio/
The pulse code modulation (PCM is the acronym in English of Pulse Code Modulation) is a method of modulation used to transform a signal analog into a sequence of bits ( digital signal ) method invented by British engineer Alec Reeves in 1937 and that it is the standard form of digital audio in computers, compact discs, digital telephony, and ...
What is PCM Audio? [Format Difference. Expert Explaned]
https://samplerateconverter.com/educational/pcm-audio
PCM audio (Pulse-Code Modulation) is one of representations of an analog signal in digital form. The representation process is called as "coding analog signal to digital form". In simple words, PCM audio is representation of usual continuous analog signal as number sequence (discrete samples).

PCM (Pulse Code Modulation): a system for representing a sampled signal as a series of multi-bit words. This is the technology used in audio CDs. PDM (Pulse Density Modulation): a system for representing a sampled signal as a stream of single bits. Sampling rate is the rate at which a signal is sampled to produce a discrete-time representation.
