Hi,
I'm relatively new to matlab and am wondering how to go about mapping a
PCM, pulse code modulated signal(8bit resolution)eg a .wav file, to a 1 bit
Pulse Width Modulated Signal in Matlab.
I understand the theory behind PWM but i'm finding it quite difficult to
implement this mapping in matlab.
Any help/code would be very much appreciated.
Thanks in advance,
Colin.
PCM to PWM mapping in Matlab?

Hi Colin,
You can try 'modulate' function from the Signal Processing Toolbox with the 'pwm' option.
Below is a simple example:
x=(1:15)/16;
Fc=1;
Fs;
y=modulate(x,Fc,Fs,'pwm');
stem(y)
