Now Available - FilterSim Version 2.0

[Gareth Jones]

SYSTOLIX HAVE RELEASED FILTERSIM VERION 2.0 - INTEGRATED FILTER DESIGN,
SIMULATION AND ANALYSIS

A fully working trial version of FilterSim 2.0 can be downloaded now from
Systolix web site at http://www.systolix.com/swdownload.htm. FilterSim is
the latest DSP development tool from Systolix. It combines a sophisticated
multi-stage filter design tool with an integrated digital simulator.
Simulation results can be viewed using the built-in signal viewer and
analysis tools, allowing designers to study filter characteristics and
quantisation effects in detail. Version 2.0 is a complete rewrite of the
tool, it includes a new simplified user interface to streamline the process
of specifying complex multi-stage filters.

Here is a summary of the key features, more information can be found at
http://www.systolix.com/fsintro.htm.
