Matlab Code for Pulse Code Modulation

 Program:

clc;

clear all;

t = 0:0.0005:20;

partition = -1:0.1:1;

codebook = -1:0.1:1.1;

x = sin(t);

[index,quants] = quantiz(x,partition,codebook);

subplot(3,1,1);

plot(t,x);

title('Message Signal');

xlabel('Time(s) ---->')

ylabel('Amplitude(V) ---->')

subplot(3,1,2);

plot(t,quants);

title('Quantized Signal');

xlabel('Time(s) ---->')

ylabel('Amplitude(V) ---->')

y = uencode(quants,3);

subplot(3,1,3);

plot(t,y);

title('PCM Signal');

xlabel('Time(s) ---->');

ylabel('Amplitude(V) ---->')

Output:
