A PCM system is somewhat more complex than another system. Thus from the above discussion, we can conclude that a PCM system, transmits data in a coded format, that ensures secured transmission. But, this at the same time needs decoding system in order to reproduce exact message signal that increases system complexity.
Pulse-code modulation (PCM) is a method used to digitally represent analog signals. It is the standard form of digital audio in computers, compact discs, digital telephony and other digital audio applications. In a PCM stream, the amplitude of the analog signal is sampled at uniform intervals, and each sample is quantized to the nearest value ...
Pulse Code Modulation techniques are used to produce a series of numbers or digits in binary form. Hence this process is called digital modulation. The amplitude at that particular time of the signal sample is indicated by the binary codes. In the PCM process, a sequence of coded pulses indicates the message signal.

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. To obtain a PCM signal from an analog signal at the source (transmitter) of a communications ...
Apr 15, 2016 · Pulse-code modulation or PCM is known as a digital pulse modulation technique . In fact, the pulse-code modulation is quite complex as compared to the analog pulse modulation techniques i.e. PAM, PWM and PPM, in the sense that the message signal is subjected to a great number of operations . In PCM an anlog signal or information is converted ...
Nov 29, 2023 · Pulse Code Modulation, also known as PCM, is a common method of converting analog signals into digital signals. Pulse Code Modulation is a method used to digitally represent sampled analog signals. It is the standard form for digital audio in computers, CDs, digital telephony, and other digital audio applications.

Pulse Code Modulation. Modulation is the process of varying one or more parameters of a carrier signal in accordance with the instantaneous values of the message signal. The message signal is the signal which is being transmitted for communication and the carrier signal is a high frequency signal which has no data, but is used for long distance ...
