how to genrate random signal

N=1024;

[Geoff Hayes]

irfan - please provide more details. What should the frequency be? What should be the amplitude? Or are these random too? Is N defined to be the block size?

[Rick Rosson]

And, what probability distribution do you want to use? Gaussian? Uniform? Exponential? Or...?

[irfan]
