File Information
Description

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.
Required Products MATLAB
MATLAB release MATLAB 7.13 (2011b)

Thanks.
Do you have BP filter design Toolbox?

Great! It would be interesting to have passive filter designs too.

hello Sir i need to know how can i implement a 4th order chebychev filter? actually we are working on sound based UGV and to filter out the noise factors we would need chebychev filters of 4th order 8 of them. so i need ur urgent help and cooperation in this regard...will be pleased to hear from you soon...
