What is PCM?
PCM (Pulse-Code Modulation) is a method used to digitally represent sampled analog signals. It is the standard form of digital audio in computers, compact discs, digital telephony and other digital audio applications. PCM involves sampling an analog signal at regular intervals, and then quantizing each sample to the nearest value within a range of digital steps. This creates a digital representation of the analog signal, which can then be transmitted or stored. It is commonly used in audio and video processing due to its high fidelity and relative simplicity.
