A combination of high and low pass filters connected in series with an overlap between the lower and upper freqencies, usually used for the mid-range in a 3-way component system.
A filter that transmits a specific band of energy and rejects all other energy at higher and lower wavelengths
Filter designed to transmit a band of frequencies while rejecting all others.
An electronic circuit that passes signals that are within a certain frequency range (band) but blocks or attenuates signals both above and below the band.
Filter that passes only a specific band of frequencies
A device which passes a range of signal frequencies and rejects those outside that range.
In mobile electronics, a device which incorporates both high-pass and low-pass filters in order to limit and attenuate both ends of the frequency range.
A passive electronic circuit that allows a narrow range of frequencies to pass through the device while blocking or attenuating higher and lower frequencies. Crystals are used for narrow bandpass filters.
A circuit designed to allow only frequencies within a specific range to pass. The cutoff frequencies must be finite and nonzero. The band of frequencies between the cutoff frequencies is the passband.
a device that, when fed a signal, allows only the frequencies within a narrow band to pass
an electronic device or circuit that allows signals between
A frequency sensitive AC circuit that allows incoming frequencies within a certain band to pass through but attenuates frequencies that are below or above this band.
Optical filter that allows transmittance over a particular wavelength range while restricting the transmittance of wavelengths above and below this range. Also known as interference filter. Also see Optics Tutorial.
A signal filter designed to pass a continuous range of frequencies, while attenuating frequencies which are both above and below that range.
An oscillator that accentuates only the frequencies in an intermediate range and rejects high and low frequencies. Implemented by first applying a low pass filter to the data and then a high pass filter to the resulting data (e.g., two SMA crossover system).
A filter that has a finite passband. The bandpass frequencies are measured at the -3 dB points.
A combination of a lowpass and highpass filter. The bandpass filter has rapidly decreasing output above and below its 3dB frequencies.
A device which allows certain frequencies to pass with less attenuation than other frequencies
A bandpass filter combines a high-pass filter and low-pass filter, allowing a certain band of frequencies to pass while restricting the higher and lower frequencies. Bandpass filters can be fixed in frequency and bandwidth, or variable.
A filter that amplifies a range of desired frequencies, called the pass band, and rejects higher and lower frequencies, called the stop bands. The filtering can be done through circuitry or by software.
A circuit which allows a certain band of frequencies to pass.
A filter whose frequencies are between given upper and lower cutoff values, while substantially attenuating all frequencies outside these values (this band).
A filter that passes one band of frequencies and rejects both higher and lower frequencies.
(BAND PASS FILTER) - (1) A WAVE FILTER with a single transmission band, neither of the cutoff frequencies being zero or infinity.  (2) A FILTER that allows a select range of frequencies to pass while attenuating all frequencies outside the range. [ 10:45
An algorithm that rejects high and low frequencies and passes only the frequencies in a predetermined range.
An electronic network which transfers through it a specific band of signal frequencies.
A two-part filter that attenuates both high and low frequencies at specific points, allowing the specific frequencies between these two points to pass.
An absorbing filter which allows a known range of wavelengths to pass, blocking those of lower or higher frequency.
A wave filter that has a single transmission band extending from a lower cutoff frequency greater than zero to a finite upper cutoff frequency.
A circuit or device that allows only a specified range of frequencies to pass from input to output.
A type of Filter used to eliminate high- and low-range frequencies around a specific frequency, resulting in more distinctive sound.
A filter that allows a specific range to pass. The bandpass frequencies are normally associated with frequencies that define the half power points, i.e. the -3 dB points. In multi-driver speaker systems, for example, the mid-range driver may be fed by a bandpass filter.
An electronic component that allows some frequencies of a signal to be passed with negligible loss in strength (amplitude) while other frequencies are either blocked or passed with reduced strength. In pacing, the bandpass filter is intended to selectively separate cardiac depolarization signals from repolarization and extracardiac signals.
A circuit which will transmit signals at particular frequencies or groups of frequencies (bands) while attenuating others.
A filter that is transparent for a range of wavelengths and opaque (reflective or absorptive) for wavelengths outside this bandpass region.
A filter that passes a band or range of frequencies but sharply attenuates or rejects frequencies outside the band.
digital, electrical, or mechanical system designed to attenuate all signals outside a specified frequency band, while passing signals within this band relatively unchanged.
A filter that has a limited passband between two frequencies. Neither of the cutoff frequencies being zero or infinite. The bandpass frequencies are normally defined as the frequencies that are attenuated -3 dB from the passband.
A filter that allows a narrow band of frequencies to pass through the circuit. Rejects or attenuates frequencies that are either higher or lower than the desired band of frequencies. A filter that ideally passes all frequencies between two non-zero finite limits and bars all frequencies not within the limits. The cutoff frequencies are usually taken to be the 3-dB points.
