Filter Synthesis Software

Feature Comparison Summary

FilterSolutions® and FilterQuick™ are Windows® based software programs for the synthesis and analysis of electronic filter circuits. The modules available in these programs comprise: Passive Filter, Distributed Filter, Active Filter, Digital Filter, Switched Capacitor, and Zmatch™ (used for creating impedance matching circuits). FilterQuick, which is included in FilterSolutions. offers a simplified interface for initiating designs which are then usable with either FilterQuick or FilterSolutions' advance feature sets. 

Licenses for FilterSolutions can be purchased as "FilterSolutions-PRO™" which contains all the modules.  Alternatively, the modules can each be licensed individually.

The "PRO" licenses include the Zmatch™ Impedance Matching Circuit module. The Distributed Element License includes the Distributed Element version of Zmatch. The Passive Module includes the Lumped Element version of Zmatch.

FilterSolutions and its individual modules are available in a network license configuration or as a MAC Address-Locked or "Dongle"-Locked, single user license.

FilterQuick, included in FilterSolutions has a reduced feature set interface.  FilterQuick contains all of the modules.  

FilterFree is a "freeware" version of FilterSolutions and can be downloaded here: (DOWNLOAD LINK).  FilterFree's capabilities are limited to 3rd Order analog designs or to 10-tap FIR designs.  All analyses in FilterFree are limited to ideal transfer functions.
