Background Nov 18, 2018 · A band-stop, notch or reject filter has two cutoff frequencies of -3dB either side of a notch, and has a stop band that is dependent on the 'Q' of the circuit. There is no gain of an RLC band-stop filter, only unity at all other frequencies except the notch, which would amount to a negative number in dB, or attenuation.
A band-stop filter prevents wavelengths within the range of the stop-band from transmitting. This is useful for filtering out unwanted wavelength regions from a spectrum. Band-stop filters are commonly included in many kinds of optical measurement setups, where they are used to prevent stray laser light from entering the sensitive detector ... Higher-order filter alignments use more components to give a sharper, more defined roll-off in attenuation of unwanted noise. For example, Elliptic (Cauer) filters give the sharpest roll-off and are the least sensitive to component variation. As a trade-off, there is more pass-band ripple and stop-band ripple in Elliptic LC filters. RLC Band-Pass Filter Design Tool. This page is a web application that design a RLC band-pass filter.
