| ScopeFIR | By: Iowegian International
Corporation (dspGuru's parent company) For: Windows
XP / 2000 / Me / 98 / 95 / NT We may be biased, but we think ScopeFIR is the very best FIR filter design program available. ScopeFIR designs FIR filters using the Parks-McClellan method, as well as several other popular FIR filter design methods. Its highly refined, multi-window graphical user interface (including multi-level zooming!) makes it very productive to use. And it provides a large number features to help you fully analyze and customize your filter design. Best of all, ScopeFIR costs only $199, which also makes it the best value in professional-quality FIR filter design software. If ScopeFIR saves even a few hours of your time (as we believe it will!), it will quickly pay for itself. ScopeFIR has a 60-day free trial period, so we encourage you to try it for yourself by downloading it from the Iowegian web site. |

| Open Source |
"Open Source" is simply software whose source code is publically available. (See our "OpenDSP" section for additional open and/or free DSP software. Also, if you're looking for filter design "routines" rather than filter design "applications", be sure to see Charles Poynton's Filter Design Software page.)
