Boki, you really should work on your English writing skills. While
just a little bit charming, your English is so fractured sometimes we
can't tell exactly what you meant to say. For example, did you mean,
"I saw an audio circuit schematic, and was amazed at how simple it
looked." Or did you mean, "... was amazed at how simple it was to
design," but then we'd wonder how you determined that.
Or perhaps you meant, "I was amazed at the simple solution to what I
had learned was complicated to design," although then we'd wonder what
you had in mind.
Too much difference from school...
Did you mean, "It looked different from anything I was taught."? But
why would that be amazing? Most industrially-produced designs look
quite different from what you find in a textbook or on a blackboard.
Your next stage of learning can be to study the production designs of
hundreds of skilled engineers, to see their approaches and to learn
new tricks. I have done that by analyzing instrument service-manual
schematics since I was a teenager. And when my oceanographic company
shipped its instruments, we always included full schematics. Sadly,
these days the manuals of new instruments routinely omit or hide the
schematics, but old manuals can be purchased on eBay, or are available
on the web in some cases.
