Active notch filters have been used in the past for applications like elimination of 50- and 60-Hz hum components. They have proven to be somewhat problematic from the standpoints of center fre-quency (f 0) tuning, stability, and repeatability. The advent of high-speed amplifiers opens the possi-bility of higher-speed notch filters—but are they actually producible?

Notch filter. A notch filter is a frequency filter that passes all frequencies 

The diagram below shows an op amp circuit for an active notch filter using a single operational amplifier and a few additional electronic components. The notch filter circuit is quite straightforward and the electronic circuit design calculations for the component values are also easy to determine. 7 - Notch filter.

Notch filter

If the filter is wideband, it is referred to as a band-reject filter and if the filter is narrow-band, it is referred to as a notch filter. Notch filters can be useful on the command for a fixed-frequency noise source such as that from line frequency (50 or 60 Hz) noise. Notch filters are also used to remove resonances from the system. Both notch and low-pass filters can cure resonance; notch filters do so while creating less phase lag in the control loop. Notch Filters are Optical Filters that selectively reject a portion of the spectrum, while transmitting all other wavelengths.

It is a very simple filter, so the frequency response is not great, but it might be all you need. Use notch filters to suppress noise at a specified frequency, such as an AC powerline frequency.

The active notch filter is a parallel combination of low pass filter and high pass filter with the Passive Notch Filter. The passive filter comprises only passive components such as resistors, inductors, and capacitors Optical Notch Filter. A Notch Notch filters, especially those with high Qs and/or high attenuations, are the most difficult to implement with universal switched-capacitor filter devices.You may design a notch filter with FilterCAD, with specifications that purport to yield a stopband attenuation of greater than 60dB, and find that in practice an attenuation of 40dB or less is the result.
