B)does not affect Rin.
C)decreases Rin and increases voltage gain.
D)increases Rin and decreases voltage gain.

Question

Quizplus · Accepted Answer

Removing the emitter bypass capacitor in a common-emitter amplifier increases the input resistance (Rin) because the emitter is no longer shorted to AC signals, making the emitter resistance (Re) part of the input impedance. This also decreases the voltage gain because the presence of Re in the signal path without bypass decreases the amplifier's ability to amplify small signals, as a significant portion of the input signal is dropped across Re.
