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.
