SYNThesis of FILters

SYNTFIL package

Syntfil is a package for Maple™ which allows design analog electrical filters. The Syntfil enables to solve approximation task, synthesis of LC ladder filters and active RC filters (ARC) including facilities for analysis of designed filter structures.

Syntfil package has three main parts:

  1. Set of functions for solving approximation tasks:
  2. Set of functions for LC filter synthesis from gain and characteristic functions:
  3. Cascade design of analog RC (ARC) filters:
