A filter which allows only a selected band of frequencies to pass through while rejecting all other frequencies above and below the cutoff point. Usually a bandpass filter will allow the user to set the width of the passband.
BPF - A reactive circuit which rejects signals whose frequencies are outside of its passband 3 dB point frequencies and propagates signals whose frequencies are within B189the 3 dB point frequencies.
A circuit that will allow signals within a desired frequency band to pass through but prohibits signals outside this frequency band from penetrating.
a filter that passes frequencies in a desired range and attenuates frequencies below and above
allows only the band of frequencies surrounding the cutoff frequency to pass through unaffected.
A filter that is transparent for a range of wavelengths and opaque (reflective or absorptive) for wavelengths outside this band pass region.
An active or passive circuit which allows signals within the desired frequency band to pass through but impedes signals outside this pass band from getting through.
An optical or detector filter which permits the passage of a narrow band of the total Spectrum. It excludes or is opaque to all other wavelengths.
A device that only passes signals within a specific range of frequencies.
A band pass filter defines a range of vibration frequencies – the filter bandwidth - within which all frequencies are allowed to pass, thus rejecting or attenuating all frequencies above and below the band.
An electronic filter which limits the effect of frequencies either side of a desired frequency range.
A crossover circuit that combines a low pass and high pass filter to create a passband.
A filter that removes from a signal all frequencies apart from those around a set frequency.
An active or passive circuit which allows signals with the desired frequency range to pass through but impedes signals outside of this frequency range from getting through. This type of filter is used mainly when adjacent frequencies are causing interference with the desired frequencies.
