A
An electrical network designed to perform frequency selection.
2
Q
Attenuation
A
A reduction in frequency amplitude.
3
Q
Gain
A
The ability of a filter to alter the amplitude of the frequency response.
4
Q
Cut off Frequency
A
The frequency at which the attenuation of a filter reduces the output amplitude to 70.7% of its value in the pass band.
5
Q
Magnification factor
A
The ratio of the centre frequency to bandwidth.
6
Q
Notch frequency
A
The frequency of the band stop filter where the maximum attenuation is obtained.
