This repository contains the code and documentation for a Pulse Code Modulation (PCM) project. The project was implemented in two parts: a MATLAB simulation and a hardware realization of the circuit.

The process results in a stepped waveform resembling the source signal. The difference between the sample and the value assigned to it is known as the quantization noise (or quantization error).

Graph signals are signals indexed by nodes of the graph. Graph Signal Processing (GSP) extends Discrete Signal Processing (DSP) to graph signals.In this paper, we explore shifting, convolution, and ...

Delta modulation is a technique of encoding analog signals into digital bits by comparing the difference between successive samples. PCM, or pulse code modulation, is another technique that ...

Figure 3-11. Spectra of frequency-modulated signals with various values of modulation index for a constant modulation frequency. It can be seen that for small values of the modulation index M (e.g. M ...

Pulse-code modulation (PCM) and delta modulation (DM) are two methods of converting analog signals into digital signals. Both methods are widely used in electronic engineering for communication ...

Pulse Code Modulation (PCM) is a method used to digitally represent analog signals. It involves sampling the analog signal at regular intervals, quantizing each sample into a digital value, and then ...
