8.2.1.2 Detailed Design Procedure

The Filter Design Tool is a simple, powerful, and easy-to-use active filter design program. The Filter Design Tool lets you create optimized filter designs using a selection of TI operational amplifiers and passive components from TI's vendor partners.

Available as a web based tool from the Design tools and simulation website, the Filter Design Tool allows you to design, optimize, and simulate complete multistage active-filter solutions within minutes.
