Someone explain amp board?

[DJSlowfets]

Would really like to learn all the internals of mobile amplifiers whether class AB or D if that plays any role in differences in the board if someone could link me or pull an amp gut pic off the Internet and break down each part not every cap and mosfet but what goes to what and what they do. Understand I'm asking alot but it's not for just me hopefully other people see your guy's response. Thanks!

MOSFETs are Metal Oxide Field Effect Transistors that class D amps use as switching devices

Filtering capacitors are present near the output of the board and are involved in filtering/demodulation.

Power supplies are large coils of wire near the power inputs on the board.

Was going to do a long writeup here, but decided to just link my English paper. It goes even more in-depth with full and half bridge topologies, but amplifier classes are in the beginning. Try to read and understand it all if it's not too boring for ya //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Thanks, lol.

Not copied and pasted. We turned them in to turnitin.com

I wish I could have made it more technical. I also had to add some filler crap, because it's an English paper. Some parts you can ignore

More specifically - there's an "amplifier" page that has a drawing of a basic board layout. You can click on each component which links you to the page that explains what each one does.
