What is notch filter is there any difference between Notch and band-stop filter?
A notch filter is a type of band-stop filter, which is a filter that attenuates frequencies within a specific range while passing all other frequencies unaltered. For a notch filter, this range of frequencies is very narrow. The range of frequencies that a band-stop filter attenuates is called the stopband.
What is the purpose of a notch filter?
The notch filters are generally used to reject a particular frequency from a system. For example, the noise of 50 Hz or 60 Hz due to power-line interference can be easily removed from different systems using notch filters.
What are 3 types of filters?
Four Major Types of Filters
The four primary types of filters include the low-pass filter, the high-pass filter, the band-pass filter, and the notch filter (or the band-reject or band-stop filter).
What is the opposite of a notch filter?
Notch filters are in essence the opposite of a bandpass filter which only transmit light within a narrow wavelength range while rejecting (or attenuating) over most wavelengths.
