Which filter shows narrower band width?
The Q-factor is the reciprocal of the fractional bandwidth. A high-Q filter will have a narrow passband and a low-Q filter will have a wide passband. These are respectively referred to as narrow-band and wide-band filters.
What is narrow band filter?
A narrow bandpass filter is a specialized optical filter designed to isolate a narrow region while rejecting all other wavelengths of light.
Which type of filter lets a narrow band of frequencies around the cutoff through?
Notch filters by design have a very narrow and very deep stop band around their center frequency with the width of the notch being described by its selectivity Q in exactly the same way as resonance frequency peaks in RLC circuits. The most common notch filter design is the twin-T notch filter network.
What kind of filter would be used to select a single frequency from many?
A band-pass filter may also be called a band-select filter as it selects a specific frequency range to pass a signal unattenuated. This type of filter is the most frequently used.
