Perfect!

this is a great video! awesome having the visual & the explanation. Plus in a relatively quick video. thank you

great video!... how do u made the visual explicaction?, any software?, i´d like to try it too

Thank you for the explanation. Perfect level of technical and lay person detail for me.

Wow, thank you for the explanation!

Amazing video, very clear and informative thank you

Link to the Udemy course? Thanks

wow, this a really good video

What software did he use ?. Link to udemy course

Great video, are you Czech? your accent sounds familiar

Visioracer?

Hi,what is the software you used for simulation

Hey man! What are you doing with that cursor? What is the purpose of that meaninigless movement which takes our attention?

Dude. Stop waving your mouse non-stop while you talk. I literally got dizzy when I was watching, I had to stop and just listen. Also, you didn't actually explain HOW do we get an analog signal at the output, which is why I started watching at the first place. WHY do we get a steep curve at the output when the pulse is wider??

Getting an analog signal out of a digital signal (like PWM) is provided by filtering out the sampling frequency. When we do that, all the pulse "spikes" (high or low only) will dissapear and merge into an average value. That's how PWM can reproduce an analog amplitude. On the other hand is frequency reproduction. In PWM, that is "coded" into the amount of wide pulses and narrow pulses. It's the combination between them what makes amplitude and frequency. It's difficult stuff. If you're still struggling with this stuff, read about FM, Frequency Modulation. That's the analog "sister" of PWM. Good luck!

i actually *have* add, very severely, and i still managed to tune out the cursor. man, kids these days, lol....

DONT jig the fg mouse please. This is terrible

The mouse is so irritating that this one begs for a thumb down 👎🏻

i don't understand all of this. I only have one question. How does a class D amplifier drive speakers directly? A friend told me that a class D amp, has a very quick power supply that can switch on and off at the rate of sound. And that a microprocessor controls the switching of this power supply, and this in turn drives the speaker-drivers directly in realtime. Is this true?

not - analog is converted to digital PWM (this is important!) and after amplify this pulses converted to analog by low-pass filter (LC usualy)

Perfect!
