WebAug 21, 2024 · You could skip the use of buttord, and instead just pick an order for the filter and see if it meets your filtering criterion. To generate the filter coefficients for a bandpass filter, give butter() the filter order, the cutoff frequencies Wn=[low, high] (expressed as the fraction of the Nyquist frequency, which is half the sampling frequency ... WebThis means that the required band-reject filter is. h b r, L H [ n] = h l p f, L [ n] + h h p f, H [ n]. Hence, a band-reject filter can be created from a low-pass and a high-pass filter with appropriate cutoff frequencies by adding the two filters. The example band-reject filter of Figure 2 has f L = 0.1 and f H = 0.4, with again b = 0.08.
