Hi, all,
I would like to generate a white noise of which the PSD is 1( flat over all
frequency domain). I used wgn function to get it:
w=wgn(1,10000,1,'linear');
By setting p=1 and power type as linear, does it mean that this white gaussian
noise has power=1?
Then I did simple experiment to check its PSD. I used periodogram function
without any window:
[p,ww]=periodogram(w);
figure; plot(ww,p);
But the plot was totally noisy instead of any flat looking. Shouldn't the
PSD of a white noise be flat in theory?
Could you guys check if I made mistake? And can you figure a way to generate
white noise whose PSD is 1?
Any suggestion will be appreciated.
