What is Q in notch filter?
Second Order Notch Filters
An equivalent way of designing the filter is to specify the quality factor and obtain the 3 dB bandwidth. Quality factor is defined as the ratio of the notch or peak frequency F 0 and the 3 dB bandwidth BW . Mathematically, Q factor is given by Q = F 0 / BW .
What is the meaning of notch 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 term is used for the frequency range control in a band notch filter?
A Notch Filter is also known as a Band Stop filter or Band Reject Filter. These filters reject/attenuate signals in a specific frequency band called the stop band frequency range and pass the signals above and below this band.
What is notch in EQ?
A word used to describe a very narrow band of frequencies to be cut by an equalizer. When an EQ circuit has a very high Q (narrow bandwidth) it is sometimes referred to as a notch filter.
