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

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

Thanks for your reply,

I can not generate square wave by coding and I have to simulate it using blocks. Because Matlab codes can not be converted to DSP board. As I mentioned earlier, the blocks also must be discrete time based blocks. I have already used the "Discrete time PWM" block of Matlab. But it did not work. The compiler recognized this block as a continues time block. Do you have any suggestion in this regard?

I assume you mean Simulink. Sorry - I do not have Simulink. I didn't know Simulink was required because you didn't list that in the Products or Tags. I will put it there for you so other people will know. I thought you could put MATLAB code into blocks but since I don't have it, I'm not sure.
