This portion of code allows to do bandpass filtering over time series

Copy this code and paste it in your HTML
  1. import scipy.signal as sp
  2. nyf= sampfr/2 #Sampling Frequency/2 (Nyquist Frequency)
  3. low=0.5/nyf #Lower cut of the filter
  4. high=50/fso2 #High Cut of the filter
  5. b,a = sp.butter(5,[low,high], btype='band') #Butter generates the coefficients for the filter
  6. dataF=sp.lfilter(b, a, data) #Does the convoultion, and the output is the filtered signal
