Question

Hello all,

The following is a brief set of guidelines the professor spoke about in class:

It is possible there are missing numbers (or numbers that don't make sense) in some of these equations, if this is the case we are to find numbers (either online and referenced or made up to fit the problem) that would make sense with the problem.

Grade is based on efforts and accuracy

A well written yet brief report showing your analytical work and output simulation is required.

A fully functioning MATLAB/SIMULINK code should be attached as well.

There should be brief discussion for the results including but not limited to comparison between analytical results and simulation, reasoning for some of the outputs, etc.

Thank you Chegg participants!

Explanation / Answer

Automatic gain control (AGC; also called automatic voltage gain) is a closed-loop feedback regulating circuit, the purpose of which is to provide a controlled signal amplitude at its output, despite variation of the amplitude in the input signal. The average or peak output signal level is used to dynamically adjust the input-to-output gain to a suitable value, enabling the circuit to work satisfactorily with a greater range of input signal levels. It is used in most radio receivers to equalise the average volume (loudness) of different radio stations due to differences in received signal strength, as well as variations in a single station's radio signal due to fading. Without AGC the sound emitted from an AM radio receiver would vary to an extreme extent from a weak to a strong signal; the AGC effectively reduces the volume if the signal is strong and raises it when it is weaker.

Since we can not add any file here but i can guide you with the steps to be followed.

step 1 : Draw the above circuit using the MATLAB and the parameters given above which I feel would be that hard.

step 2 : at the output ,one can connect the scope or anything which shows the digital data .

step 3: start varying the input B, and note the corresponding variation in the output .

step4: if the small variation in input results in small variation in output .that means the system is BIBO stable which means that all the parameters here given are correct.now since it is told that we have to find the missing term .so the above theory will difinately fail and you will get large variation in the output.

step 4 : try varrying some of the parameters in the feedback path .i hope you will definately get the results .
