Question: A voltage-follower amplifier comes to you for service. You find the voltage gain to be 5.5 and the input impedance 22 k . The probable fault in this amplifier, if any, is
Options
A : the gain is too low for this type of amplifier.
B : the input impedance is too high for this amplifier.
C : nothing is wrong. The trouble must be somewhere else.
D : none of these.
