Web1 de fev. de 2024 · A notch filter is a type of band-stop filter whose stop band is narrow. An ideal notch filter rejects only the band-reject frequency and allows all other frequencies to pass, thereby removing only the 50- or 60-Hz electrical noise.9 However, no filter is ideal; it is well known that filtering can distort the original signal.
