New Video: Essential & Practical Circuit Analysis Part 2: Op-Amps

[TimNJ]

Hi everyone,

I've been meaning to put out the second part of my circuit analysis series for a long time (more than a year). And I finally got around to recording it recently.

This video takes you from the basics, all the way through the typical building block circuits, and applications.

Enjoy!

That's a great video!  Thanks.

I seem to have had a little trouble when it came to analog computers.  Somehow the video plays longer than the time shown when it first starts but quits right after the diagram of the suspension system.

It turns out that my only interest in op amps IS analog computing.  It's kind of fun modeling equations I had a heck of a time solving in college.

Thanks! The video seems to work fine for me. I'll see if anyone else says they have problems.

Analog computing really interests me too. Even bought a few books from the 50s and 60s. But unfortunately, I havent had much time to work on any hardware. GK has done some amazing things though.

Glad you liked the video. Thanks.

It played fine this time.

I have been thinking about buying an arbitrary waveform generator for the specific purpose of providing x(t).  A more cost effective scheme might use a DAC on an Arduino...

This is the analog computer I built and it works very well.  It has just enough integrators (2) to do the equations of motion.  It has sin(t) and a multiplier plus 2 summing amplifiers and an inverter.  All it does is make me want a larger analog computer!
