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

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

Step 1: Understand that a common-emitter BJT configuration is a type of amplifier circuit.
Step 2: Identify the input signal, which is applied to the base of the BJT.
Step 3: Identify the output signal, which is taken from the collector of the BJT.
Step 4: Recognize that in this configuration, when the input signal increases (goes positive), the output signal decreases (goes negative).
Step 5: Conclude that the output signal is out of phase with the input signal, meaning they move in opposite directions.
