MATLAB signal processing: knowing order of FIR filter to be designed
For didactical purposes i want to create a lowpass FIR filter (of any type, Equiripple will be ok) that attenuate an ‘omega1’ frequency (example: 0.3 rad/s, normalized) of at least 80 dB.
different method of bandpass filtering. fftfilt non working properly
i need to bandpass filter vibration data
