FilterLab simplifies active filter design, offering an easy-to-use, free tool that supports various filter types like low-pass, high-pass, band-pass, and anti-aliasing filters. It provides the flexibility to select filter topologies, specify component tolerances, and optimize designs. FilterLab generates downloadable schematics with component values and a complete Bill of Materials (BoM). With FilterLab, users can also view real-time gain and phase response plots.
