Active high pass filters pass signals from high frequencies and reject signals from low frequencies

RF filters and microwave filters are devices that pass or reject signals by frequency.

Industrial filtration equipment is used to filter, thicken or clarify a mixture of different elements

Signal filters block or decrease (attenuate) unwanted frequencies or signal wave characteristics

Liquid filtration elements are used to remove impurities from liquids.

Filtration media and elements are designed to remove suspended particles from a process stream.

Active low pass filters pass signals from low frequencies and reject signals from high frequencies
