How does a class D amplifier work? (Udemy Course)

[@tomglanville]

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

[@rayamahony9987]

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

[@juancarrillo1424]

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

[@sandwich.entity3810]

Amazing video, very clear and informative thank you

[@alexandruc.5128]

Link to the Udemy course? Thanks

[@samanrubab4376]

while compiling this circuit on orcad we need mosfet model where to find them

[@SimonYells]

Wow, thank you for the explanation!

[@vigneshkarthi3321]

What software did he use ?. Link to udemy course

[@pecilijevelicanstveni4973]

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

[@carstenweber7676]

Exactly! I was, at first thinking he might be a little retarded, but the quality of the video speaks against that theroy.

[@pecilijevelicanstveni4973]

@@carstenweber7676 Video is perfect but the movements of that cursor is irritating. That is the point.

Hi,what is the software you used for simulation

Falstad, it's a website.

hey does "parallel" mean anything particularly significant to you? if so i totally know you irl, lol.

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??

[@hugoromeyn4582]

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!

[@discy12345]

Thanks. Indeed. His mouse pointer is too distracting.

[@ElTurbinado]

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

[@sc0or]

DONT jig the fg mouse please. This is terrible

[@papinkelman7695]

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

[@seankayll9017]

Unwatchable. Stop waving the flippin' mouse pointer around!

[@patrickle8514]

Terrible instructions and visuals.

[@tee-botheewok716]

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?

[@zbyseklipka406]

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

[@flaviomaia5377]

Perfect!
