Request for circuit analysis

Dear friends,
The reason why I got stuck with electronic circuits just before biasing
will be clear in a short while.
Without the support of a good teacher the logic involved appears
formidable.
The pages attached relate to transistor as an amplifier and its biasing.
The book concerned is All.new.electronics.self-teaching.guide.2008. The
questions are posted on some of the attached pages themselves. The rest
attached pages are for logical continuity and completeness.
I will try to find a way on how to get those pages uploaded and then get
back.
Please help.
Regards

you forgot the part about asking a specific question and what
specifically you don't understand. No one is going to do you
home work for you, you could at least pretend you tried to make
an effort

That's NOT how it works. You are asking a bunch of complete strangers -
many of us highly paid professionals - to give up some of our time to
answer your questions. The LEAST you have to do is to ask the questions
here so those of us who have no particular interest in the SPECIFIC
question can pass over it and to get the attention of those who wish to
answer.

Read "How to ask questions the smart way" at:
<http://www.catb.org/esr/faqs/smart-questions.html>

Then ask your question HERE. We wont do your homework for you but if you
make an attempt are likely to help you correct it.

I wanted to save your time by posting my questions on the pages
themselves. I believe it would definitely save your time.

Mate, just post the questions one at a time. Then there will be no
confusion and you can consider the answers before posting the next.

Cheers ....... R.P

There are no friggin pages here.

The pages are in:
https://docs.google.com/folder/d/0B0qPAe-7HylCLU5OV0xtNmtSaU0/edit
Page 249 has a circuit diagram.
Problem 9 is given near end of page and continues in Page 250. The
Problem 10 refers to the same circuit and defines voltage gain by a
formula. How this formula is derived?
Instability and solution is given in Page 253, Problem 11 and a circuit
diagram is given. Then formula for gain is given. But how this formula is
derived?
Page 256 has a problem 17 continued in page 257. Steps are given. But if
the gain part can not be derived then the solution can not be arrived at,
which are continued in page 258.

The url you posted does not display large enough in either IE
or Firefox 16.0.1. What is visible does not show a diagram on
page 249.

To get answers, you will need to find a better way to ask your
questions. I'll try to give you a method: "ASCII art"

Here is what I can make out on page 248 in "ASCII art"
(Not shown is the sine wave input and inverted sine wave output)

You can use the above diagram (if it is the one you have in mind)
to ask your question.

Or you can find another way. We can't help if we can't see.

[snip overly generalized questions]

The images are too small to read. And using the zoom in IE9 actually makes
the image smaller.

From what I can see, you have no idea how to apply Ohms Law, and you don't
understand basic transistor characteristics such as Vbe diode junction and
current gain. You may need to go back a few (hundred) pages and comprehend
the basic principles of circuit components.

Have you ever actually built a simple circuit?

Have you tried using a simulator like LTSpice?

Two hints concerning ASCII art and circuit diagrams:
You *MUST* use a fixed pitch font to view ASCII art or the lines dont
match up vertically. If you don't know which font to use, try "Courier New".

There's a utility for Windows called AAcircuit that helps you draw ASCII
art circuit diagrams. <http://www.tech-chat.de/aacircuit.html>
Simply use it to edit your diagram till you are happy with it, then use
its menu option to copy to clipboard, then paste into your next
newsgroup posting. The program is German but you can also select
English or Danish.

Dear friends,

The reason why I got stuck with electronic circuits just before biasing

will be clear in a short while.

Without the support of a good teacher the logic involved appears

formidable.

The pages attached relate to transistor as an amplifier and its biasing.

The book concerned is All.new.electronics.self-teaching.guide.2008. The

questions are posted on some of the attached pages themselves. The rest

attached pages are for logical continuity and completeness.

I will try to find a way on how to get those pages uploaded and then get

back.

Please help.

You're not going to learn much from a book like that, it is just recipes. The gain equation for the uncompensated config beta x Rc/ hie is more symbolic than numerical since hie is all over the map depending on collector current swing.

Around 1970 I wrote a tutorial on biasing for ICE, but haven't been able
to locate a copy. The following example MAY be of help to you...

while I look around for the write-up of more generalized methods.

And I would be eagerly waiting...
