See filter.

high-pass filter

[′hī ‚pas ′fil·tər]
(electronics)
A filter that transmits all frequencies above a given cutoff frequency and substantially attenuates all others.

high-pass filter

A filter that blocks low frequencies and allows higher frequencies to pass through. Such filters are used in devices such as POTS splitters that direct phone and DSL signals to different lines. Contrast with low-pass filter.

You connect the input leg of each adapter to the left- and right-channel preamp outputs, connect one output leg of each to cables leading to the dual line-level inputs to the sub, and connect the remaining output leg of each to cables leading to the high-pass device.
We determined the effects of filtering on elevation localization accuracy for signals presented in front of and behind the head by averaging the perceived elevation of signals presented from each elevation at the 0 [degrees] and 20 [degrees] and the 160 [degrees] and 180 [degrees] azimuths, respectively, for each low- and high-pass filter cutoff frequency.
If the high-pass filter for both of the mid-bass drivers is 80 Hz, then it only makes sense to have the low-pass frequency locked in to properly accommodate that roll-off.
New features of the software include a real-time oscilloscope signal monitor with residual THD+N values; an optimal reference level that can be set with automated regulation; and additional high-pass, low-pass, and weighting filters.
also high-pass filter the signals to the satellites.
Diplexers contain both low- and high-pass filters, to selectively transmit low- and high-frequency signals, respectively.
The series include low-pass, high-pass, band-reject and bandpass filters, and can also be used as delay lines, with desirable control of group delay distortion.
Additional filtering options include a programmable high-pass filter, for wind noise and other extraneous noise reduction, a programmable IIR filter and an advanced programmable ALC with noise gate in the ADC path.
The series includes low-pass, high-pass, band-reject and bandpass filters and can also be used as delay lines.
The Z-A431PJ31X-A contains three filters: one plain old telephone service (POTS) low-pass filter to protect the alarm panel from DSL interference, a second POTS low-pass filter to protect DSL from impedance changes in the alarm panel, and a high-pass DSL filter to ensure ongoing DSL service, even during an alarm call.
