There's something wrong with the formula I used to introduce noise on my sequence:
obviously, talking about a autocorrelation of rectangular sequences, it has to be a triangle: the central sample should be > of left and right neighbours, so I decided to plot the probability that central sample...
Hi everybody guys, I'm writing a signal processing software using C, so I'm a little bit "stuck".
I generated a triangular sampled signal. I need to add white gaussian noise to it at a certain SNR.
I calculated the power of autocorrelation as:
\[\frac{1}{N}\sum_{i=0}^{N-1}x^{2}\]
and then...
