Hi

where in Matlab, would you be more precise in what you want?

ASK works as follows:

- take sine wave at RF (Radio Frequency - high frequency)
- take the digital data (like square wave) where logical "1" is equal to 1; logical "0" is equal to 0
- multiplicate them

On the output you will have a slide of RF sine wave each time when logical "1" is sended/transmitted, and nothing when logical "0" i sended/transmitted

That's all. I hope it helps
Regards

Re: help for ASK

Hi
First ASK works as follows:
If the data is 0 then the ouput after ask will be 0
If the data is 1 then the ouput will be the same as the carrier.
So simply the matlab code will be:
f=1*10^6; as an example
t=1;
x=sin(2*pi*f*t);
source=randint(1,128);
y=x*source;
