High-pass filter Definition & Meaning - Merriam-Webster

WebJul 30, 2024 · High pass filters are filters used in RF and wireless applications to reject low-frequency components from a signal and pass the high-frequency range. These filters are used in many applications for frequency selectivity and provide higher isolation from low-frequency components. WebThis theory lets us know what information we can recover from the discrete data ... The high-pass filters technique is often used to clean up low-frequency noise, and to highlight the high-frequency trends (Rioul et al., 1991).
