The amplifier in the Figure below has a variable gain control, using a potentiometer for Re with the wiper bypass ac-grounded. As the potentiometer is adjusted, more or less of Re is bypassed to ground, thus varying the gain. The total Re remains constant to dc, keeping the bias fixed. (a) Determine the maximum and minimum gains for this unloaded amplifier. (b)Find the overall maximum and minimum voltage gains for the amplifier with a load 1k12 if it is being driven by a 300 k22 source.
