Block diagram of Pulse Code Modulation. The figure below shows the block diagram representing a PCM system. 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 basic operations in the receiver section are regeneration of impaired signals, decoding, and reconstruction of the quantized pulse train. Following is the block diagram of PCM which represents the basic elements of both the transmitter and the receiver sections.

A pulse code modulation system includes a transmitter like a PCM encoder & a receiver like a PCM decoder. The important operations within the transmitter of pulse code modulation mainly include sampling, quantizing, and encoding.

Apr 1, 2025 · Pulse Code Modulation (PCM) is a digital modulation technique where the analog signal is coded into digital pulses. Here, we will see the block diagram of the PCM system or Pulse Code Modulation system to understand its working principle.

Aug 24, 2023 · Pulse-code modulation (PCM) is a method used to digitally represent sampled analog signals. Learn its block diagram, steps, types, advantages, and applications. English

Apr 15, 2016 · PCM Receiver. Fig. 5 shows the block diagram of a PCM receiver . Fig.5 : PCM Receiver. The regenerator at the start of PCM receiver reshapes the pulse and removes the noise. This signal is then converted to parallel digital words for each sample.

Sep 16, 2023 · Pulse code modulation (PCM) is a digital modulation technique by which analog signal gets converted into digital form for transmission, storage, or processing. It involves sampling, quantizing, encoding, and, if needed, reconstructing the original analog signal.

Pulse Code Modulation & Demodulation Aim: Generate Pulse code Modulation and Demodulation. Experimental Requirements: PC Loaded with MATLAB Block Diagram: (a) Transmission Path Decoder (b) Receiver MatLab Program: % Pulse code modulation & Demodulation clc; clear all; close all; a=4; fm=2; fs=100*fm; …

Mar 17, 2025 · Different modulation techniques use different parameters to transmit a signal from the transmitter to the receiver. Here, we will discuss the PCM (Pulse Code Modulation) technique, one of the digital modulation methods to transmit the signal.

Pulse Code Modulation (PCM) is different from the other forms of pulse modulation studied so far, PCM also uses sampling techniques, but it differs from the others in that it is a digital process.
