Filter Design

Filter design refers to the process of creating systems that selectively allow certain signals to pass through while blocking others. This is commonly used in electronics, audio processing, and communications. For example, in audio systems, a filter can enhance bass sounds while reducing high-pitched noise. Filters can be designed for various frequencies, such as low-pass (allowing low frequencies), high-pass (allowing high frequencies), band-pass (allowing a specific range), and band-stop (blocking a specific range). The goal is to improve overall performance, clarity, or quality of the signal being processed.
