Analog filter design

Analog filter design involves creating electronic circuits that selectively allow certain frequencies of signals to pass through while blocking others. These filters are used in audio processing, communication systems, and other electronics to shape or clean signals. Designers choose components like resistors, capacitors, and inductors to craft filters with specific characteristics—such as low-pass, high-pass, band-pass, or band-stop—based on the desired frequency range. The goal is to control signal behavior smoothly and reliably in real-time, ensuring the system functions effectively without distortion or noise.
