Active Options
  Partial filters may be regrouped or have their individual amplifications changed
  Poles & Zeros can be rearranged
  Substitution of low, medium, and high quality partial filter structures

 

 Component values are either shown as precise values or the best possible match made from series or parallel connection of a set of user defined standard values
  
Passive Options
Circuit topologies and values may be changes or reordered. Reverse, dual and wo-port manipulations are available
Variations in the filters are also possible using Norton/Impedance transformation and Pi-to-Tee conversion
Component quality (Q) factors may be assigned
Terminating resistor values can be changed

Professional

In the past, designing filters required a great deal of technical knowledge, as well as the ability and patience to work with detailed tables and text books. But today things are different. With FilterMaster Professional designers can produce results in a fraction of the time required using older methods. FilterMaster is a highly specialized CAE tool that synthesizes passive filters. It allows the designer to easily optimize filter spcifications and investigate the filter transfer characteristics.

The capabilities of this program go far beyond what can be accomplished with "classical" filter cookbooks. FilterMaster is capable of generating approximations of much greater complexity then those found in data books. But because FilterMaster is so easy to use, even non-specialists can develop high quality, minimum cost filters.

The result for those who use FilterMaster Professional : design manufacturing time are reduced, design errors are eliminated, and the time to market for new products is greatly diminished. In many cases the price of the program will be recouped with your very first filter.
