Notch Filter Product Introduction:
A notch filter, also known as a band-stop filter, is a precision filter designed to suppress specific narrow-band frequencies while allowing signals of all other frequencies to pass through with almost no loss. Its core function is to eliminate narrow-band interference.
The working principle is to form a deep attenuation notch around the target frequency Fo. Systems of the second order and above can achieve ideal notch characteristics. In digital circuits, the second-order IIR (Infinite Impulse Response) structure is predominantly adopted, which is realized through zero-pole placement.
