This is only a second order filter. Depending on the exact properties of your signal, this may not be enough to isolate the component that you want. I'd recommended a Butterworth bandpass filter. In this case you can independently control the lower cutoff and the higher cutoff of your bandpass and also the steepness of the slopes. There are butterworth design tools in "Octave", see

Design IIR Butterworth Filters Using 12 Lines of Code

Butterworth filters exhibited a ripple free frequency response with a -20*n Db/decade roll-off at the cutoff frequency, where n is the order of the filter. There are only three design parameters for a Butterworth filter, the order n , the cut-off frequency , and the DC gain, , or the gain at zero frequency.

A bandpass filter from 0.4 Hz to 5 Hz using a 2nd order Butterworth filter. Then the signals are normalized. All signals were sampled at 125 Hz I feel that my code has exactly that. Still not understanding why it is not working. I appreciate your help. If you can maybe explain it in a different way that would be helpful thanks.

Butterworth Filter Design Equations and Calculations

Slope of 2nd order low pass vs band pass Butterworth filters. Ask Question 0. 1. I have noticed that some manufacturers of audio processing products label a 2nd order Butterworth low pass as having a slope of 12dB per octave, but then also label a 2nd order Butterworth band pass as having a slope of 12dB per octave. In actuality each side of a 2nd order Butterworth band pass has a slope of
