Vedclass · Answer

(B) In a common-emitter transistor amplifier, the input signal is applied to the base-emitter junction, and the output is taken from the collector-emitter junction. Due to the nature of the transistor action in the common-emitter configuration, the output signal is inverted with respect to the input signal. This means there is a phase difference of $180^{\circ}$ between the input and output signals. If the input signal starts with a positive half-cycle, the output signal will start with a negative half-cycle. Figure $B$ correctly depicts this $180^{\circ}$ phase shift, where the output signal is the mirror image of the input signal across the time axis.

Which of the following figures correctly shows the phase relation between the input signal and the output signal of a common-emitter transistor amplifier?
