The notch filter
WebNotch filters are used to remove a single frequency or a narrow band of frequencies. In audio systems, a notch filter can be used to remove interfering frequencies such as powerline … WebMar 29, 2024 · You don't really take a typical highpass filter for DC removal. The more precise approach is more of a notch filter at ω = 0. You can achieve this by placing zeros at s = 0 and the same number of poles at positions slightly shifted into the causal real half plane and imaginary part vanishing.
