FilterExpress 4.0 includes companion – Brief Article

Systolix has released version 4.0 of its digital filter design software, FilterExpress, and has added a companion simulator called FilterSim.

The Windows-based tools provide electronic and comms systems designers with a rapid means of developing and evaluating DSP-based filters of almost any kind, according to the company.

Once a filter configuration has been created, it can be simulated with FilterSim using built-in signal generator facilities or a user’s own test data. The numeric precision of the tools is user-programmable to allow filter designs to be optimised for the target DSP hardware. When satisfied with the results, the filter’s coefficients may be saved in ASCII format for import into a user’s DSP development software.
