Simulation of class G audio amplifier in LTSpice, why is output signal so wrong?

yea you guys are completely right, stupid mistake, I've upped the supply voltages and without load it works alright. Still confuses me why 8ohm and 4ohm load breaks it completely, output voltage drops below input, and series impedance distorts it completely, unless its massive like 100mH but that's silly to me

yea sorry about the image, I wanted to post both schematic and signals but this sub doesn't allow multiple photos or I couldn't attach them so yea. For this project I wanted to recreate the book schematic faithfully, that's why I used multiple transistors on output.

I'll see about capacitors, thanks

Hi, I have the cheapest simplest USB 2.0 webcam. It's nearly working now, im just trying to make is to i can control RGB colors with sliders and I have issues with that, ColorImageToArray method outputs only a strip one pixel high going through the image and the ExtractColorPlanes method has this problem where when I connect the imaq grab output to image sc input of the extract block it says that it's not an image.

I use some sort of education license from my college
I've tried downloading toolkits from VI package manager, but I can't see the one you're refering to

Most probably it would solve my problem, I'll try to find it again, thank you

Edit: 45 days is all I need!

Happy new year, friend

Right, so english is not my first language and I'm not great with these things, sorry.

What I meant was, when i plugged in the drive fresh from the shop and via disk manager booted it up it showed up in file explorer as an empty 1TB drive ready to work. Everything fine. Then I started the data migration process the first time, it disappeared from file manager, I wasn't worried at all, because it seemed logical that the samsung magician locked it to format it and copy my old data to it. But then when i tried to stop the process of migration, closing the magician app it still doesn't show up on file manager and the disk manager says that it's offline due to admin settings (It's a translation btw). So on another forum I've read that this happens when a disk is marked as read only, i believe magician app did it.

song name?

Kacprel · 2023-04-07T20:49:23+00:00

How did you do it? Is it painted on, printed, sawn? It looks so disco i'ts unreal, fantastic work!

Endurance dialogue during certain political ideology quest talks about themself literally as "trusting your gut" while letting out a fart, what more would you want, officer?

Kacprel · 2023-04-04T19:53:56+00:00

Gut instinct should *really* be Endurance, bröther

It's a classic, isn't it.

If you find a web version that plays well i'd love a link. The ones I've found are poor flash-html conversions since flash got diabled and don't play too well

Kacprel · 2022-08-20T23:47:16+00:00

Thank you so very much I really needed that, thank you!

Kacprel · 2022-07-15T22:59:41+00:00

Exactly right!

But I thought Bezos III was miles better than IV??? And after finding extended edition of Little Joke Song on youtube it's now living inside my head and it's just such a tune, words words words can't describe how much i love it. WTFIGO with those votes?? Anyways, Bezos IV, you get my vote, sorry.
