This is a particular type of filter that passes all frequencies above a certain frequency.
This filter passes all frequencies above and rejects all frequencies below a specified corner frequency.
A filter that rejects low frequencies below a set frequency, typically 100 Hz.
a filter that allows only those frequencies above a so-called limit frequency (called the crossover point or cutoff) to pass
a filter that passes high frequencies and attenuates low frequencies
A filter used to pass frequencies higher than a predetermined point. Frequencies lower than the F3, or crossover point, are attenuated at a rate determined by the design of the filter.
A reactive circuit that rejects signals whose frequencies are below the 3 dB point frequency and passes signals whose frequencies are above the 3 dB point frequency.
A filter that allows high frequencies to pass through.
A filter designed to pass high frequencies while attenuating low frequencies.
A network of components, which attenuate all frequencies below a predetermined frequency selected by the designer. Frequencies above cut-off are passed without any effect.
This filter cuts out the low and midrange tones, delivering only high frequency's range notes to your tweeters.
A circuit that discriminates between high and low frequencies and allows only the high frequencies to pass.
A network of elements used to attenuate all frequencies below a predetermined frequency. Frequencies above the cutoff point pass without any effect. also see: AKA: Antonym: Source: http://www.the12volt.com/glossary/glossary.asp
Passes detailed high frequency image information, while attenuating low frequency, slow changing data.
A tuned circuit designed to pass all frequencies above a designated cut-off frequency. Frequencies below the cut-off frequency are rejected or attenuated.
A device that blocks signals below a specific frequency while allowing signals above that frequency to pass.
This is a device that filters out any frequencies below the crossover frequency.
A filter that removes from a signal frequencies below a certain set frequency.
A device or network of components that blocks low (bass) frequencies below a designated point, and allows high frequencies to pass.
When a low-level transducer signal is superimposed on a large dc output voltage, a high-pass filter might be useful. This attenuates (removes) low frequencies. Using a cut-off frequency of, say, 4 Hz, will eliminate the dc voltage which has a frequency of zero. A high-pass filter will remove "drift". This can be a particular problem with biological and chemical signals, but not usually with modern electronic signals. See Issue 8 of our newsletter for more information.
