QuickFil is now Freeware
The filter design software QuickFil is a program which was originally developed under DOS. It allows calculating passive electronic filters up to the 50th order in a quick and efficient way.
With specially designed fast mathimatical algorithms and arithmetic routines in assembler language, QuickFil is still one of the the fastest passive filter design softwares on the market. This was also the reason why we migrated QuickFil to the windows environment. But with the start of the 64 bit area, it seemed that QuickFil had come to an end.
Luckily, we found a workaround which allows to run QuickFil also under Windows Vista and Windows 7. And so it is now possible to offer you our old-fashioned but high performance filter design software as Freeware.
