Notch Filter

 

Narrow notch filters are used in Raman spectroscopy and instrument amplifiers to reduce or prevent audio feedback, while having little noticeable effect on the rest of the frequency spectrum. Other names include 'band limit filter', 'T-notch filter', 'band-elimination filter', and 'band-reject filter'.
