How do you get the active filter calculator to work? I keep getting syntax errors no matter what I try. I entered 120 for cutoff and .1 uf under cap ( as it recommended to start with)
I tried entering different values under the R! R@ and the C! C2 fields but no dice.

Nevermind, determined it was not accepting the value I gave it as being practical. 1 uf was acceptable. Syntax error does not exactly inform you what is wrong with the suggestion but alls well that ends well.

nice program though, I will send the developers a xmas gift donation for it. I like it alot.

I was just playing with it. Seems you have to put the caps in as 0.1 or you get an error message. Try it and see what happens

If your designing low pass it would not work unless I put in 1 or 2 No matter what frequency I tried .1 was persona non grata

The R value calculated end up being pretty high. Not sure why I can't start out with .1

I am working my way through their readme file to see if there is a clue, So far I see where he made uf acceptable instead of 10 -6

I foigured it out. It needs 0.1 instead of just .1
