My question is easy one actually.
First, I generate a random signal using
randn() function of MATLAB like this:
Then, I design a FIR filter of order 200 of pass-band characteristics with the pass-band $[0.2\pi, 0.4\pi]$ using the MATLAB function
My questions are:
- What am I supposed to see when I filter a random signal using BPF?
- What change in the characteristics will be occur considering the theory?
