High-pass filters

High-pass filters are electronic or signal processing tools that allow high-frequency signals to pass through while reducing or blocking lower-frequency signals. Think of them like a sieve that lets through only the fine particles (high-pitched sounds or fast-changing signals) and filters out the larger, slower ones (low-pitched sounds or slow signals). They are used in audio systems to eliminate bass sounds, in communication to clear high-frequency signals, and in various technical applications to focus on rapid changes or details in a signal. Essentially, they help isolate or emphasize the high-frequency components in a variety of systems.
