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... Slept through class one to many times? I've learned that I don't suffer from insanity, I enjoy it! (The hell with my X-wife!)
