PCFILT is a serious filter design program written without useless "eye-wash". Don't expect it to look as pretty as the big-name brand software, but do expect it to design virtually any filter you need very quickly! PCFILT is loaded with powerful features that may seem hidden at first. This is for a good reason. With a little prompting from us you will be surprised at its flexibility. You will see why the largest filter company in the world has 60 (Yes, SIXTY) copies of PCFILT in use! PCFILT is also quite easy to use, but we can't expect you to know how to use it right away. When you have the demo running, call us for a guided tour of PCFILT over the phone. This is the only way to know why PCFILT is used by people who are serious about designing filters!
