Filter Tool

Filter design software portable to embedded processors. Written in plain C without library dependencies covers FIR, IIR and analog filter design. Mapping between analog and IIR biquads using bilinear transform.

Features

FIR filter  least-suqare design method.

Analog filter design Butterworth, Tschebyshev I/II, Bessel, Cauer.

IIR design from analog model.

Easily integrable in small processors.

It has been ported to PC, ARM embedded Linux and no-OS Infineon C166 Familiy.
