Whenever I try to understand explanations of how a circuit works these seem very complicated and confusing. There will be some general lines to understand how a circuit works from some transistors to a dozen or more of them. Thanks in advance.
Are you looking at old magazines or books, or circuits off the internet?
If the latter, there are lots of places that extract the circuit from some article but don't include any of the text, so there's no explanation of what the circuit is doing.
IN the old days, how descriptive a book or magazine article was depended on the book or magazine. SOme magazines had fairly good explanations, others were fairly generic.
But the trick is to keep at it, and just keep reading. When I started reading hobby electronic magazines in 1971, when I was 11 years old, most of it meant nothing to me. I was lucky the magazines had some non-technical things in it to keep me buying the issues. But there were generally tutorial articles that helped me understand things, and I was radin any book I could get my hands on, which mostly at that point meant library books.
A few months in, I copied out the list of parts for a project, went to an electronic store chosen at random, and tried to build the project, that never worked. Too many variables that I didn't have enough knowledge to figure out. That happened a few times, but within the year, I was able to get projects working, though by then I was taking things apart and reusing the parts. So if I didn't fully understand what was going on, I at least had gathered enough about what the parts did and what could be substituted, so the projects actually worked. Those first few steps are pretty big, but once you overcome them, you look back and they are no longer so big.
