Jun 10, 2013 · Plots the waveform of a Pulse Code Modulated signal. Pulse-code modulation (PCM) is a method used to digitally represent sampled analog signals. It is the standard form of digital audio in computers, Compact Discs, digital telephony and other digital audio applications.

6 days ago · This is a MATLAB code for performing Pulse Code Modulation (PCM) on an analog signal. The code generates an analog signal, samples it, quantizes it, encodes it, and finally demodulates it back to obtain the original analog signal.

Our MATLAB-based Pulse Code Modulation (PCM) System Simulator provides a comprehensive implementation of digital signal processing fundamentals. The simulator demonstrates the complete PCM chain: sampling, quantization, encoding, decoding, and signal reconstruction.

A PCM stream is a digital representation of an analog signal, in which the magnitude of the analogue signal is sampled regularly at uniform intervals, with each sample being quantized to the nearest value within a range of digital steps.

1. Performance of Waveform Coding Using PCM. Generate a sinusoidal waveform with a DC offset so that it takes only positive amplitude value. Sample and quantize the signal using an uniform quantizer with number of representation levels L. Vary L. Represent each value using decimal to binary encoder. Compute the signal-to-noise ratio in dB.

Oct 1, 2013 · Modeling PCM communication systems with the pulse code system by programming, and conduct computer simulation by MATLAB, to analysis performance of the linear PCM and logarithmic PCM.

The document describes an experiment to study pulse code modulation (PCM) using Matlab. PCM converts an analog signal into a digital signal using sampling, quantization, and encoding. The experiment involves writing a Matlab program to generate a PCM-encoded cosine wave.

This project implements a MATLAB simulator for a Pulse Code Modulation (PCM) system. The simulator models each system block, including Sampler, Quantizer, Encoder, Decoder, and Reconstruction Filter, as separate functions.
