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

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.

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.

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

@oldolfmann8927 8 ай бұрын

I bet you think it is composed of many frequencies

@sto2779 8 ай бұрын

@@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.

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)

@gigadabyte 3 жыл бұрын

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

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!
