Digital filter design

Digital filter design involves creating algorithms that modify or refine digital signals, such as audio or sensor data. These filters can remove unwanted noise, enhance certain frequencies, or extract specific information from the signal. The process involves defining a mathematical model that determines how the filter responds to different parts of the input. Designers select parameters to achieve desired effects, ensuring the filter performs accurately and efficiently. This process is fundamental in many technologies, from audio processing to communications, enabling clearer, more useful digital signals.
