Control Theory
A high-pass filter is an electronic circuit or system that allows signals with a frequency higher than a certain cutoff frequency to pass through while attenuating signals with lower frequencies. This type of filter is crucial in various applications, including audio processing and communication systems, to eliminate unwanted low-frequency noise and enhance signal clarity. High-pass filters are commonly implemented using resistors and capacitors in electrical systems, making them essential for optimizing performance in diverse scenarios.
