1. A narrow band filter, such as a notch filter , requires low damping. 2. This limitation may preclude its use in some low-pass and notch filters . 3. Adaptive algorithms are often used to automatically tune these notch filters . 4. *"'notch filter to reject the cross modulation products must be used at the output. 5. Or search for " notch filter " on the Web for plenty of sources. 6. The user can select a low-pass filter, high-pass filter, band-pass filter, or notch filter . 7. You might consider a type of notch filter , or detuning by a half step. 8. These are notch filters usually in an array of six, eight, and sometimes four units. 9. As well, these amplifiers often contain feedback-suppressing devices, such as notch filters or parametric equalizers. 10. Parametric equalization and notch filters are commonly used by sound engineers to manually control feedback.
