Default Please Help me urgently

Attend class, stay awake, take notes, study, pass simple exam question.

Getting the answer here or from Google is called plagiarism. You get an
'F' if the instructor finds out.

Hello,
I can not handle a problem which is about AGC. Please help me about
that. The conditions are;
It is required to design and implement an AGC circuit
with the following specifcations:
1. Amplitude of the input voltage may vary between 10 mVpp and 50 mVpp.

2. Amplitude of the output voltage should be in the range 0.9 Vpp
and1.1 V
pp for the input signals with amplitudes stated above.

3. Output impedance of the ampliŻer should be smaller than 2 k*.

4. The circuit should be able to amplify the signals having frequencies
between 500 Hz and 10000 Hz.

The amplifer designed should be a single transistor amplifer in the
common-emitter form for BJT amplifers or common-source form for the
FET amplifers. However, it can be used extra transistors for making the
amplifer an adjustable gain amplifer.

And the AGC should be composed of 2 parts adjustable gain part and
feedback part.

Please help me urgently to design this problem. Thanks...

It's a technology race, and the instructors are well ahead.

Dissertations can now be scanned by Google-type software that looks for
copying. Whatever literature resources the student could have used, the
department has access to the same and more.

A friend told of a recent example of a final year dissertation on 2.4GHz
LNA design. The software easily found the un-referenced Agilent
Application Note that the student had copied. They had already been
warned...

Dear Ian:
The worst case that I encountered was the finding of a direct copy of my
own work in a student's thesis! I was not amused!

On the other hand, I recently was faculty advisor on a thesis of
exceptional quality and originality. The student had performed some
valuable and original work with nano-technology. The student's care in
crediting each and every idea that was used and every person who helped
(including skilled technicians) was a model of what should be done. The
best students know, and acknowledge, their antecedents, mentors and then
delineate what they have done that is new.

I offer the above as an example that not all is lost.

Warm regards, Mac N8TT

Had the same happen to me: read an article in a German radio magazine
that was written exactly as I would have... no, dammit, it was written
exactly as I already HAD, in a different magazine!

exceptional quality and originality. The student had performed some

Oh, indeed it isn't. The friend who told me about the copy-detection
software had spent 20 years of his life as a rock musician, but is now
headed for a First Class honours degree in RF Engineering. Needless to
say, he's an active ham.

Glad to hear there is still integrity in some circles.

Hey Dave.... From where do you suppose the instructor got the question?
Besides we really don't know if the class is in EE or on computer web
sites and the internet!.....WB3HUH

Simply "getting" the answer from google is not wrong or unethical - any
more than looking up the answer in a textbook.

It is what you do with it after you get it. that is the issue. I do my
research in textbooks, reference volumes, and google. It's all good. As
long as it is correct.

Some of this creeping codgerism sounds like the old rants against
calculators..... and I'll bet slide rules before that! ;^)
