I notice that many users here have access to drawing software that enables nifty figures. Where can I get software like this - preferably for free, if possible. Thanks much.
Much of what you see here is done using ltspice which can be found here. There are also tutorials as to how to use it. There are other good free schematic softwares out there also. A Google of "free schematic software" or "free schematic capture" will bring up plenty of software suits for doing schematics.
Thanks Ron. I also found some old posts on this forum with other recommendations. I shoulda done this first, but I didn't realize there was so much freely available.
