please make available a copy of filterpro 2.0. I just got a new computer and thus got v3.0 instead but I prefer 2.0 since you can specify both C1 and C2 without the other getting recalculated. I do this to design filters using the capacitors I have in house. With v3.0 I can only specify one and the other most likely ends up with a value that we don't have.
I've added this as a feature request for future enhancement of FilterPro 3.
In the meantime, with the understanding that it is no longer supported, we have made FilterPro v2 available on our ftp site: ftp://ftp.ti.com/pub/linear_apps/filter_pro/
Please refer to this FAQ for differences between FilterPro 2 and FilterPro 3, as well as a list of known bugs in FilterPro 2.
I agree with Thomas. This is a feature that has caused me to revert to v2 of FilterPro.
I agree with you guys too! I did the same
Rick you posted previously :
"...Yes, in FilterPro2, you could specify both C1 and C2, and then the
software would recalculate the other components; this applied to all stages. With FilterPro3, as you stated, you can change a component value (ANY component value) and the other components in that
stage will be computed. This is more flexible, I think, because it lets
you optimize one stage for, say, a high input impedance, without having
to do it for all the other stages."
I could not change the components' value. How do you do that? Thanks for the for the FTP link.
From the FilterPro 3 user guide:
"Items in the schematic are either red or blue.
Red Label: Items in red are not available for editing. These are labels identifying certain aspects of the
Blue Label: Items in blue are available for editing. Change the component values by hovering the
mouse cursor to the value of the component and clicking it. You should see a box around the number
in blue. Enter the value that needs to be changed. "
Make sure you hit the "Enter" key after changing the number so that the value is updated and the other component values in that stage are recalculated.
filterpro 2.0 is no longer on the ftp site. Any idea where I can get it?
Yes, it appears to have disappeared. I don't have another place to point you to right now, but will look into what happened here, and get back to you.
Any luck finding FilterPro 2?
I finally managed to find the link to the FTP site to download FilterPro v2, but alas it seems to have disappeared. Is there any hope of getting it back? I second all the options presented here -- version 2 was really an awesome little tool.
FilterPro 2 is a long time out of circulation. At this time we do not have the capability to send it your way. I would suggest you look at FilterPro 3 (which I think you have) and Filter Architecture (Beta version) in the WEBENCH area on the web. In particular, what is it that FilterPro 2 gave you. I will find out if this is possible with Filter Architecture, as we are in the middle of developing the final version right now.

Hi Bonnie, thanks for your reply. I managed to get a copy of FilterPro 2 from a friend, so I'm good. The main thing that FilterPro 2 allowed me to do is quickly tweak any of the component values or the 3 dB point and it would recalculate the others, keeping fixed the components I had nailed down. It made it very easy to get a working filter based on the limited set of component values I happen to have on hand at any given time.
