Pulse Code Modulation -MATLAB Code

Pulse Code Modulation MATLAB Code

Important to note this that this is a function file not script, you need to pass parameters to execute this program.

Step 1. Save "pcm.m" in your current directory of MATLAB

Step 2. define parameters A, fm, fs, n as rquired e.g. A=2, fm=3, fs=20, n=3

Step 3. then write [y Bitrate MSE Stepsize QNoise] = pcm(A,fm,fs,n)

Or After step 1 just write [y Bitrate MSE Stepsize QNoise]=pcm(2,3,20,3) in command window

Explainantion

Explaination of parameters is as follow

A = amplitute of cosine signal

fm = frequency of cosine signal

fs = sampling frequency

n = number of bits per sample

y = binary output

MSE= Mean Squar error

QNoise = Quantization Noise

Example

[y Bitrate MSE Stepsize QNoise] = pcm(2,3,20,3) or y = pcm(2,3,20,3)
