Brilliant demo and explanation. Thanks for sharing!

Applied Science Ben and Alan, you guys should meet up and do a video.

Frédéric Dutrey I would *LOVE* that - too bad we're at opposite sides of the country!

***** If only there was a means by which you could collaborate and share data in real time over long distances. I long for the day when that becomes reality.

Yeah, maybe when someone figures out this inter web thingy ;-)

The Signal Path Blog Yes, there's nothing like "seeing" things like this - really makes it "click!" Thanks for the comment!

***** Can you make a video explaining type 1 through 3 op amp compensation networks used for switch mode power supplies? Also, what does the "s" mean in (s+1) term in control theory for compensators and what does the H(s) function stand for?

EETechs H(s) is the transfer function of the loop expressed using LaPlace transforms. This would be a more complicated topic and would likely have to encompass a few videos. I'll put it on the list though.

Michael Lloyd I agree. I've never saw anyone else do it as good as he does.

You just have to find youtube instructors that explain things in a way that works for YOU! I'm glad that my videos do that for you.

Unfortunately, I wasn't a very good student (and that's my fault), but I do think Alan's videos are much more educational than any lectures I received in my EE baccalaureate degree program; my lab classes didn't even use real oscilloscope probes (and, I had no knowledge what additional influences a home-made probe would have introduced , when high frequencies were used in a circuit- besides, we didn't have the equipment to generate anything over 200 megahertz, anyway, if my memory serves me well). We just used coaxial cables, stripped to the conductor on one end, with a BNC connector on the other end. It's embarrassing for me to admit, how much basic electronic science I've learned from Alan's videos - that I should have already know from my formal education as a EE student. I sure hope my university does a better job today educating future engineers - but, I doubt they do, since I can't imagine the lab classes having expensive modern electronic test equipment in them (too expensive). It blows my mind to think of the money wasted in education, when they could just buy some decent test equipment, and pay the correct people to demonstrate how to properly use the test gear - and what the equipment is measuring, and why; And I do believe in the idea of public education, and consider myself to be very much a liberal. However, just today I was reading, in our local paper, about our local convention center receiving an education award for educating children middle school and high school children- not sure of the exact grades; this convention center puts on these very silly plays, which are supposed to be comical (I guess), for which they bus in thousands of kids to watch, during the school day, and call this science education. I started watching one of the plays concerning science, and it was a joke (truly a joke), IMHO.

@@WECB640 I think Walter did a great job with the pendulum explanation.

one more animated visualization from me (made in HFSS) for coax line ypylypenko.livejournal.com/42947.html

Maybe I'll teach after I retire...

Thank you Gerry!

Yes, yes exactly!
