an electronic circuit that lets through frequencies between two other given frequencies
A filter, which passes only signal frequencies within a specified, continuous frequency band, and predictably attenuates frequencies above and below the continuous band.
A filter that only allows a single range of frequencies to pass through.
A filter with a single transmission band extending from lower to upper cutoff frequencies. The width of the band is normally determined by the separation of frequencies at which amplitude is attenuated by 3 dB (a factor 0.707 ).
An electric circuit designed to pass only a certain range of frequencies. See also High-pass and Low-pass filters.
An electric circuit designed to pass only middle frequencies.
A band-pass filter only transmits light components with a specified wavelength. The band-pass filter incorporated into the VG Series receiver has a characteristic that only passes light components with the wavelength of the semiconductor laser used in the VG.
A tuned circuit designed to pass a band of frequencies between a lower cut-off frequency (f1) and a higher cut-off frequency (f2). Frequencies above and below the pass band are heavily attenuated.
A filter that passes frequencies within a certain range and blocks all others. A filter designed to pass all frequencies that fall between f and f.
a circuit that passes a range of frequencies and attenuates signals above and below this range.
A band-pass filter is a device that passes frequencies within a certain range and rejects (attenuates) frequencies outside that range. An example of an analogue electronic band-pass filter is an RLC circuit (a resistor-inductor-capacitor circuit). These filters can also be created by combining a low-pass filter with a high-pass filter.
