Butterworth notch reject filter
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. WebBand Reject Filters • Notch Filters.
