band-stop filter
bandstop filter

A band-stop filter passes frequencies above and below a certain range.

Power line hum can be alleviated using a band-stop filter.

A band-stop filter passes high and low frequencies outside of a specified band.

A very narrow band-stop filter is known as a notch filter.

The band-stop filter is generally wide enough to reduce clutter, in addition to the bleed-through signal.

Often band-stop filters are described alternatively as rejection filters.

It does this by removing part of the orange region of the color spectrum, acting as an optical band-stop filter.

Notch filter - rejects just one specific frequency - an extreme band-stop filter.

Figure 14 is a band-stop filter formed by a parallel LC circuit in series with the load.

Both band-pass and band-stop filters can be constructed and some filter circuits are shown later in the article.

This is known as the pinna notch, where the pinna creates a Band-stop filter effect.

A band-stop filter has one stopband, specified by two non-zero and non-infinite corner frequencies.

This modulation prevents these frequencies from propagating within the grating, acting as a band-stop filter.

For instance low-pass, high-pass, band-pass and band-stop filters can all be produced from the same prototype.

A notch filter is a band-stop filter with a narrow stopband (high Q factor).

Band-stop filter or band-reject filter - only frequencies in a frequency band are attenuated.

Dielectric mirrors can be produced as low-pass, high-pass, band-pass, or band-stop filters.

The creation of highly selective band-pass or band-stop filters based on appropriate resonant branches has been alluded to in the previous section.

The difference between the limits in the band-stop filter is the stopband bandwidth, which usually is expressed in hertz.

Fortunately band-pass and band-stop filters can be constructed from just capacitors and resistors, thereby avoiding the inductive problem.

The band-stop filter used as a feed-through nuller is typically 1kHz, which attenuates signals in the center of the band-pass filter.

In the general sense, frequency ranges can be emphasized or attenuated using low-pass, high-pass, band-pass or band-stop filters.

Foster's second form of driving point impedance consists of series connected LC anti-resonators and is most useful for band-stop filters.

A passive feed-through nuller uses a band-stop filter to reduce low-frequency signals before digital signal sampling, and this includes the bleed-through signal.

Resultingly the parallel connected circuit will act as band-stop filter having infinite impedance at the resonant frequency of the LC circuit.
