hello bobi,
Actually i had suggested to my instructor to implement an AGC . I too dont know the answer
to your question .I know that we have to demonstrate it with using a microphone and showing that the output voice does not vary while I move microphone away or close to my mouth . Can you please
give a brief working of the AGc (i.e what should be the mode of the gain ). I will be grateful to you .ASAP.
