Analog Filter Design Toolbox

GUI to design and simulate active (opamp) LP and HP Bessel, Butter, Cheby, and Elliptic filters.

Analog Filter Design (AFD) Toolbox allows the user to design, analyze, and simulate active analog filters easily in a graphical (GUI) environment. It was developed at MIT and is currently used in several universities to teach signal processing concepts. It can be used to build Butterworth, Bessel, Chebychev I and II, and elliptic filters. It can display time and frequency responses, pole/zero plots, transfer functions, circuit diagrams, and provides the ability to simulate filtering of user-supplied and standard data types (e.g. sinusoidal, squarewaves, EKG data).
To use, type AFD from the command prompt. The toolbox includes a comprehensive user's manual.
It has been tested to work up to Matlab R2011b, and likely will work beyond that.
