Please Help me urgently

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 ampli¯er 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...
