RE: [tracker2] Re: Rough Time Line for production units and feature request.
- Still trying to figure that out. The worst is the output filter, which isn't even strictly necessary. I just wanted it there in case I want to experiment with higher speed modes where you might not be able to count on the radio filtering out the PWM artifacts. I've got some filter designing software, too (plus LTSpice for simulation) but I think I modeled the problem incorrectly. I think I also made a boneheaded mistake on the input filter and put the diode limiter in the wrong place.Scott

Oh? How so? Just curious...
I do have a shareware (I think, haven't used it for a while) program
that designs various sorts of filters - Op-amp, RC, LC, Transmission
line (Stub), and a few others, that might help with this...
