Active notch filters were actively used during the earlier decades for amplifier and audio applications for eliminating of 50- and 60-Hz hum interferences. These networks have been although somewhat awkward from the standpoints of center notch frequency (f0) tuning, balance, and consistency.

Notch Filter. Notch Filter sharply attenuates frequency-specific noise like mains hum or electrical whistle with minimal damage to the remaining audio, by cutting a "notch" out of the frequency spectrum at that point. Accessed by: Effect > Notch Filter...

Notch filter experiment. For those who don’t know what notch filter is I’ll explain in short: the task of a notch filter is to reduce the strength of the audio signal in certain frequency range. Such a filter is usually used in a single driver (also known as broadband or full-range) speaker designs. Because it has only one driver it is often very hard or impossible for such a …

the notch filter. With 800-Hz signal coming in, ad- just the notch control to a point where the signal drops in volume. On some CW sig- nals with key clicks and thumps, the 800-Hz signal will drop out but the clicks and thumps will still be there. I have found that it is easier to remove a hetero- dyne with the peaking cir-

The formula for calculating the notch frequency is, notch frequency= 1/4πRC, where π equals 3.14, R is the resistance, and C is the capacitance. Also worth pointing out is that the maximum value of the output voltage below the notch frequency is less than the maximum value of the output voltage above the notch frequency.
