Question: In a common-emitter configuration, what is the phase relationship between input and output signals?

Options:

Correct Answer: 180 degrees out of phase

Solution:

In a common-emitter configuration, the output signal is 180 degrees out of phase with the input signal.

In a common-emitter configuration, what is the phase relationship between input and output signals?

In a common-emitter configuration, what is the phase relationship between input and output signals?

Step 1: Understand what a common-emitter configuration is. It is a type of amplifier circuit using a transistor.
Step 2: Identify the input signal, which is the signal you apply to the base of the transistor.
Step 3: Identify the output signal, which is taken from the collector of the transistor.
Step 4: Learn about phase relationship. Phase refers to the position of a wave in its cycle at a given time.
Step 5: In a common-emitter configuration, when the input signal goes up (positive), the output signal goes down (negative).
Step 6: This means that the output signal is inverted compared to the input signal.
Step 7: The term '180 degrees out of phase' means that when one signal is at its maximum, the other is at its minimum.

Common-Emitter Configuration – A common-emitter configuration is a basic transistor amplifier setup where the emitter terminal is common to both the input and output circuits.
Phase Relationship – The phase relationship refers to the difference in phase angle between the input and output signals, which in this case is 180 degrees.
