A differential amplifier whose two input signals are equal, but 180 degrees out of phase, will have a/an ________ output signal.

A differential amplifier is designed to amplify the difference between two input signals while minimizing the impact of any signals common to both inputs. When the two input signals are equal but 180 degrees out of phase, this means that one signal is the negative of the other.

In this scenario, the differential amplifier will produce an output that reflects this phase difference. Since the amplifier is set to respond to the difference between the inputs, the output will be the highest possible level, as it effectively amplifies the maximum differential between the two signals. The equal magnitudes of the signals, combined with their opposing phases, lead to a situation where the output is maximized based on the design of the amplifier.

This results in a large and distinctly positive or negative output, depending on the specific arrangement of the amplifier's circuitry and the conventional definitions of phase. Therefore, the output signal is classified as a maximum in terms of amplitude, indicating that the differential amplifier excels at amplifying the full differential available when the inputs are exactly opposite in phase.
