Hi, I am having trouble creating a digital bandpass filter between the frequencies of 2-5Hz in MATLAB. I am trying to get the code to isolate the frequency in that range, and estimate the phase of dominant frequency. If you could help me design this filter, or share a similar code, that would help a alot.
Thank you!!

Hello,
You can use the bandpass function to filter the input signal with a passband frequency range with normalized units of π rad/sample. Further to estimate the phase you can use the angle function. You can find examples in the link of the mentioned functions to help you get started.
