[SciPy-User] FFT Filter
Sat Sep 24 02:33:53 CDT 2011
I am kind of new to scipy and also new to the signal processing field
that this question relates to.
I am trying to do a bandpass FFT filter using python. The filter shape
is symmetric around 11 Hz and is defined by the parameters ff and Hz below.
sr = 250 # [samples/s]
nf = sr/2.0 # Nyquist frequence
Ns = len(tr[:,0]) # Total number of samples
N=float(8192) # Fourier settings
# Fourier transform
X1 = fft(x,n=int(N))
X1 = fftshift(X1)
F1 = arange(-N/2.0,N/2.0)/N*sr
Hz = [9.5, 10, 12, 12.5]
My question is now:
Are ther built in functionallity for filtering in scioy and, if so, how
would a similar filter looks like.
