Hi all,
i have a signal vector with length=15612. With a FFT using N=2^14=16384 points i obtained spectrum of the signal. Now, i need to create a low-pass filter and a band-pass filter. I decided to use butter function but to obtain N and Wn values i need to use buttord function. But i don't understand what Wp, Ws, Rp and Rs are. I have no experience in signal processing. Can you please help me? I have already read the definitions of Wp, Ws, Rp and Rs but i don't understand anything. How can i decide on them?
Thank you
