How the circuit works

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.

 

Know how a gear works ? Know how a hydraulic piston works ? If so, you know how an automatic transmissio in a car works. It is the details.

In a THM400, in drive, as vehicle speed increases, governor pressure increases which is compared to a regulated (line) pressure and when it overcomes it pushes the piston to allow full pressure to the secon gear clutch, without taking it out of first gear because of the action of the one way clutch on first gear. this shift it inhibited by a pressure modulated by what;s called the vacuum modulator.

It is actually an analog computer. It is not even electronic except for one solenoid that dumps pressure from one line to allow it to go into passing gear, which for some configurations can take it down to forst gear as high as 70 MPH approximately.

What I have described is notning but a bunch of pistons and shit like this. Knowing what EACH of the components actully do is all you need to know what the entire circuit does.

Get to know exactly how a transistor works, and all of the components, then you just sit down and figure it out. Doing it this way is muchbetter than having someone explain every little thing to you becauswe in the future when presented with another circuit which is totally unfamiliar toy you, you know how to figure it out.

In a way, the less help you get, the better. (to a ceertain point, there are things you need to know to even get started, but too much help really can be cunterproductive)

I find your question hard to understand, you need to be more precise.

Actually, the answer is that large combinations of transistors are
really just collections of much smaller functions... think simple.

Don't let it bother you, there are many that will tell you
their side of it with a convincing explanation and not know
any more that you do about it.

Just think of politicians.

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.
