Pulse Code Modulation (PCM) is a digital representation of an analog signal. It is a technique used to convert analog signals into digital signals by quantizing and digitizing the analog signal into a series of binary numbers.
In PCM, the analog signal is sampled at regular intervals, and each sample is converted into a digital value using an analog-to-digital converter (ADC). The resulting digital values are then encoded into a stream of binary digits, which can be transmitted, stored, or processed digitally.
The advantage of PCM is that it provides a way to store and transmit analog signals in a form that is resistant to noise and interference, and that can be easily processed by digital systems. This has made PCM a widely used technique in many applications, including digital telephony, audio and video recording, and computer networks.
