What does the 60 Hz notch filter do?

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.

How do you filter 60 Hz noise?

The most common way to eliminate the noise is through a 60 Hz notch filter. Because there are inherent variations in the 60 Hz signal, a notch filter is not robust against signal source frequency changes.

What is the purpose of a 50 Hz notch filter for biomedical applications?

A notch filter is typically an aggressive filter that strongly attenuates the power over a narrow region of the spectrum. For example, a notch filter at 60 Hz / 50 Hz is used to filter out power line noise with minimal disruption to the rest of the signal.

What is the use of notch filter?

Notch filters are used to remove a single frequency or a narrow band of frequencies. In audio systems, a notch filter can be used to remove interfering frequencies such as powerline hum. Notch filters can also be used to remove a specific interfering frequency in radio receivers and software-defined radio.
