Filter design software and websites
A thread for filter design stuff, especially if it's free.
I've been using the Remez/Parkes-McLellan applet here. Looks nice and simple to use and seems to work well though I haven't actually implemented any designs yet. http://www.dsptutor.freeuk.com/index.htm More stuff, not tried any of this: http://www.icsi.berkeley.edu/~storn/fiwiz.html http://www.poynton.com/Poynton-dsp.html http://www.digitalfilterdesign.com/ http://sim.okawa-denshi.jp/en/ This is available as a very limited free version or a short term trial version if you don't want to spend the money. May well be the best package around. I believe that Tubesrule (Darryl) uses it for the digital filters in his Aurorae http://www.filter-solutions.com/ |

Re: Filter design software and websites
This is one I've been using of late -
http://www.aade.com/filter.htm It's free and the opening screen advert disappears after it's been used a few times. Parabola |

Re: Filter design software and websites
I've used that for some years. I also worked in a place that had the capacitor meter which is quite good.
It's not a substitute for knowing what you are doing, but very useful. Handy to design an elliptic filter and then tweak the peaks/notches for specific frequencies. |
