Along the lines of "please don't laugh at me but...", how does the AGC affect the bandpass, particularly its shape. I thought all the AGC did is change the gain at the various stages so the shape would be the same just translated "up" or "down" depending on the signal. Is that a horrible way to understand AGC (or its effects on the passband)?
Thanks,
