Excellent tutorial and equally valid today. Pitty the image quality is so poor that it's hard to see much detail. Probably the original film recording is no longer available and this was taken from VHS tapes or similar. I thank Mr. Carlson's Lab for pointing me to this channel.

Is it just me, or does the opening music sound like the score to nearly every 50's sci-fi movie?

good for you, sheep

Just how close is a quarter of a billionth of a second to zero rise time? well, ask how close is a billion to infinity! Such a beautiful line at the end.

"....approaching 1 and a half of a billion cycles per second" - times have changed. We now have 100 Ghz scopes at the exotic level and I have a 6Ghz scope on my bench as the 'daily driver' Fantastic film that does a nice job of explaining the content and structure of a square wave and its importance.

Thanks for posting all these videos

Love memory Lane, Intel Xenon at 4 ghz now. Thanks Mr Carlson. 2017

Such amazing explanations, excellent work for bringing back to us these awesome videos

Very very best tektronics instruments

Very educational, more so than I remember learning in electronics scool 38 years ago.

School, not Scool

Here from Carlson lab -like a lot of other people- and just like him I’ve never hit sub so quickly.

Thank you for uploading this video, at work I don't know how these things work

Brilliant!

5:30 - that makes sense... I bet most people doesn't know how a square wave is truly formed.

I bet you think it is composed of many frequencies

@@oldolfmann8927 Well isn’t this so stated on the video? However I think this is only true making square waves using analog tech. However modern square waves are digital, it is not composed of analog frequencies.

"Hey, Joe, try not to show off that HP audio generator too close." Great film, though!

excellent upload excellent video

Excellent

Good info!

I like this dramatic music haha

They were way more coherent in explaining things back then. Everything wasn't a sales pitch.

So a quarter of a billionth of a second would be a 250ps rise time....and viewing it when tubes still ruled electronics. (edit: oops, math corrected, thanks)

Correct if I'm wrong but 1e-9/4=250e-12, so 250ps. Even today that is fast. Greetings.

You did not mention the value of C1 and C2.

🤕😵

Of course we all know the answer to the last question is 42. Shouldn't even have to ask.

Picture quality is poor.

low quality and 240p? come on¬

This is how technologies develop over time. It has always been this way. It always will be this way. The film was apparently made about 60 years ago, so... no, it doesn't look the same as if it had been made last year!
