ideally a filter that passes all frequencies below its cut-off frequency and rejects those above the cut-off. In practice the cut-off characteristics are far from ideal.
A filter that allows lower frequencies than a certain predetermined frequency level to pass.
Replaces the regular filter (used for one-way transmission) on a drop, and enables a subscriber to have 2-way service. The LPF allows low frequencies to pass, but blocks out higher frequencies.
An electronic filter that allows only the frequencies lower than a given point to be heard, eliminating all frequencies above a given point. The exact filter point is equipment and/or setting specific, but is typically 6 - 12 Khz which helps eliminate sibilance and hissing. see also high cut filter
This filter passes all frequencies below and rejects all frequencies above a specified corner frequency.
A circuit that discriminates between high and low frequencies and allows only the low frequencies to pass.
a lowpass filter (given the appropriate range)
a shunt to ground for high frequencies, i
A filter used to pass frequencies lower than a predetermined point. Frequencies higher than the F-3, or crossover point, are attenuated at a rate determined by the design of the filter.
An electronic or acoustical device designed to pass all frequencies lower than the design frequency, and to attenuate, or block, all higher frequencies.
A filter that allows low frequencies to pass through.
A filter designed to pass low frequencies while attenuating high frequencies.
In data or signal analysis, a filter that passes frequencies below some cutoff frequency while attenuating higher frequencies.
The most commonly used filter in electronic keyboards. It removes frequencies above a particular cutoff point and allows frequencies below that point to pass through. (See "Filter")
A filter for leveling out the borders in the screen display of a radiology image. The image is altered by placing a value on each pixel which is the weighted sum of the pixels in a small square surrounding the pixel in the original image. The weights or filter coefficients determine how the new image will look, and the borders of the image can be leveled out ("low pass filter") or sharpened ("high pass filter").
A reactive circuit that rejects signals whose frequencies are above the 3 dB point frequency and propagates signals whose frequencies are below the 3 dB point frequency.
A digital or optical filter which passes slow changing, low frequency information, while attenuating high frequency, detailed edge information. Machine Vision The automatic acquisition and analysis of images to obtain desired data for controlling a specific activity.
A device that blocks signals above a specific frequency while allowing signals below that frequency to pass.
An electronic circuit designed to pass all frequencies below a specified frequency while attenuating signals with frequencies above the rated value.
A filter that removes from a signal frequencies above a certain set frequency.
A network of elements used to attenuate all frequencies above a predetermined frequency. Frequencies below the cutoff point pass without any effect.
A network of elements used to attenuate all frequencies above a pre-determined frequency. Frequencies below the cutoff are passed without effect.# MY SONY MEMBERS
A network of components which attenuate all frequencies above a predetermined frequency selected by the designer. Frequencies below cut-off are passed without any effect.
A device or network of components that block high frequencies at a designed point, and allows bass frequencies to pass.
This lets through the lower frequencies and attenuates the higher frequencies. Choose the cut-off frequency to be compatible with the unwanted frequencies, the frequencies present in the signal you are measuring, and the sampling rate of the analogue-to-digital converter. See Issue 8 of our newsletter for more information.
This filter cut out the mid-range and high tones, delivering only the low frequency's signals to your woofers.
