The Square Wave 1961

[@w3vjp568]

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

[@sto2779]

gives me the questionable goosebumps...

[@dualityrepair4770]

I was getting strong Twilight Zone vibes

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.

Here thx to Mr Carlsons Lab .. . Great Channel :)

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.

[@JetNmyFuture]

"....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.

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

Very very best tektronics instruments

[@materialsguy2002]

Thanks for posting all these videos

[@OctavMandru]

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

[@leeslevin7602]

Brilliant!

[@joefutofu]

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

[@MaxKoschuh]

excellent upload excellent video

[@Daveyk021]

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

[@foureyedchick]

School, not Scool

[@INeedAttentionEXE]

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

[@babakvernal6696]

Excellent

[@warphammer]

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

[@sto2779]

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

[@oldolfmann8927]

I bet you think it is composed of many frequencies

[@sto2779]

@@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.

[@Kryoclasm]

Good info!

[@grzesiek1x]

I like this dramatic music haha

[@pietromoopy2010]

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

[@andrewlindh5047]

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]

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

[@sujitsingh7446]

You did not mention the value of C1 and C2.

[@mishu9356]

🤕😵

[@sujitsingh7446]

Picture quality is poor.

[@amarissimus29]

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

[@phonotical]

low quality and 240p? come on¬

[@ydonl]

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!

[@phonotical]

@@ydonl its on 35mm film, you can blow that up to 8ki easily, this just looks like a video from a 90s server

[@ydonl]

@@phonotical I'm not sure you're being realistic.

@@ydonl youre not understanding my comment
