What is PCM sampling?

A digital technique that involves sampling an analog signal at regular intervals and coding the measured amplitude into a series of binary values, which are transmitted by modulation of a pulsed, or intermittent, carrier. It is the standard technique in telecommunications transmission.

What is a symbol in digital communication?

A symbol may be described as either a pulse in digital baseband transmission or a tone in passband transmission using modems. A symbol is a waveform, a state or a significant condition of the communication channel that persists, for a fixed period of time.

What is PCM sampling rate?

PCM with uncompressed linear quantization is used for digital audio, with a sampling rate of 48kHz currently recommended by the Audio Engineering Society (AES) for the "origination, processing, and interchange of audio programs." 44.1kHz sampling is standard for audio CDs; 96kHz is a recommended sampling frequency for ...

What is a PCM frame?

Pulse-code modulation (PCM) is a method used to digitally represent sampled analog signals. It is the standard form for digital audio in computers and various Blu-ray, Compact Disc and DVD formats, as well as other uses such as digital telephone systems.
