RFTYT Bandstop Filter Q Factor Frequency Range

Band-stop filters have the ability to block or attenuate signals in a specific frequency range, while signals outside that range remain transparent through.

Band-stop filters have two cutoff frequencies, a low cutoff frequency and a high cutoff frequency, forming a frequency range called the “passband”. Signals in the passband range will be largely unaffected by the filter. Band-stop filters form one or more frequency ranges called “stopbands” outside the passband range. The signal in the stopband range is attenuated or completely blocked by the filter.

Overview

Stopband bandwidth refers to the width of the stopband range, that is, the frequency span between the high and low cutoff frequencies. Band-stop filters have different attenuation rates, which are used to represent the degree of attenuation of the signal in the stopband range relative to the signal in the passband range. Some band-stop filters may have ripples in the passband range, that is, changes in the gain of the signal over a specific frequency range. Ripples can be controlled through filter design and optimization to ensure signal quality in the passband range. Band-stop filters typically have specific input and output impedances to match the impedance requirements of the signal source and load.

Band-stop filters are widely used in various fields, such as communication systems, audio equipment, amplifiers, radio receivers, etc.
