A high-pass filter modifies a signal only by eliminating lower frequencies.

The first, a high-pass filter in k-space, has been proposed by Gary H. Glover and colleagues at Stanford.

Images were processed with a high-pass filter to isolate objects, with the sizes comparable to single PSD clusters.

A high-pass filter is a filter that passes higher frequencies well but attenuates lower frequency components.

In diagnostic mode, the high-pass filter is set at 0.05 Hz, which allows accurate ST segments to be recorded.

Conversely, high-pass filters already incorporated in the circuitry of DSL modems filter out voice frequencies.

A low-pass filter is a circuit that allows low-frequency signals to pass through while reducing unwanted high-frequency signals from passing through.

A high-pass filter removes the lower frequencies, and the lowest frequency that can be identified with this technique is the reciprocal of twice the TR.
