What is pulse code modulation PCM explain it?
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 PCM system?
Pulse code modulation (PCM) [13] is a digital scheme for transmitting analog data. It converts an analog signal into digital form. Using PCM, it is possible to digitize all forms of analog data, including full-motion video, voice, music, telemetry, etc.
What is pulse code modulation explain briefly with proper diagram?
Block diagram of Pulse Code Modulation. It is basically composed of a transmitter, a transmission path and a receiver. The transmitter performs the sampling, quantizing and encoding of the signal. The transmission path includes regenerative receivers that recover the signal from the undesired noise effects.
What are the 3 processes of a PCM?
PCM consists of three steps which are sampling, quantization and coding. As seen in the above image an input analog signal which is in the form of a sine wave is converted into a digital signal with discrete values.
