filterhp
FilterHP refers to a high‐pass filter, a type of linear filter that allows signals with frequencies higher than a chosen cutoff frequency to pass while attenuating lower frequencies. It is commonly used in audio processing, telecommunications, and digital signal processing to remove low‑frequency noise or to isolate high‑frequency components of a signal.
A high‑pass filter can be implemented in analog or digital form. Analog realizations include simple RC circuits
Design parameters include the cutoff frequency, which is the frequency at which the output power drops to
Applications of FilterHP span audio equalization (removing low‑frequency hum), image processing (enhancing edge detail by removing
