WebI need to filter 50 Hz from a signal. It looks like the best options are either a notch filter or a LMS filter, but I don't have a copy of the noise so a notch filter seems to be the best … WebThe notch frequency for the notch filter is set by the following calculations: where, ALP = gain from input to low-pass out at f = 0Hz. AHP = gain from input to high-pass out of f >> fO. Typically, ALP/AHP • RZ2/RZ1 is equal to one. This simplifies fNOTCH to be, fNOTCH = fO where, RF = RF1 = RF2 and C = C1 = C2 Note that the notch frequency ... WebOct 25, 2015 · Filtre notch 50Hz.
