low-pass filter

[′lō ‚pas ′fil·tər]
(electricity)
A filter that transmits alternating currents below a given cutoff frequency and substantially attenuates all other currents.

low-pass filter

A filter that blocks high frequencies and allows lower 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 high-pass filter.
