What filter allows frequencies higher than its programmed frequency to pass through while blocking low frequencies?

Explanation:
High-pass filters are designed to pass frequencies above a certain cutoff while attenuating those below it. So frequencies higher than the programmed cutoff pass through with little attenuation, and low frequencies are blocked or greatly reduced. This is distinct from a low-pass filter (passes low frequencies, blocks high), a band-pass filter (passes a specific range), or a notch filter (very selectively removes a narrow range).
