MATLAB: Generating Square Wave in Matlab

Question

Hi,

I intend to generate a square wave by Matlab simulation with this characteristic:

– 20 kHz, – amplitude between 0 and 1, – it is able to be shifted.

Then, I am going to convert the square wave to a DSP board. Therefore, I have to use discrete time blocks. Because the continues time blocks are not acceptable by compiler.

Please help me to find the appropriate algorithm.

Regards Foad

Answer 1

How about using ones(), zeros(), and repmat()?
