To amplify a signal, an amplifier must be supplied with a power source, which provides the necessary energy to increase the amplitude of the input signal. Additionally, the amplifier needs a suitable input signal that it can process. The amplifier's design and gain settings determine how much the output signal will be increased relative to the input.

The amplifier that uses the base as the reference terminal for the input and output signal is the common-base amplifier. In this configuration, the input signal is applied to the emitter, while the output is taken from the collector. The common-base amplifier is known for its high frequency response and low input impedance, making it suitable for specific applications such as radio frequency amplification.
A: It always a voltage since it is a voltage amplifier
Output impedance of an amplifier refers to the resistance that the amplifier presents to its load when it is in operation. It affects how the amplifier interacts with connected devices, influencing voltage levels and power transfer. A low output impedance is generally desirable as it allows the amplifier to drive loads more effectively, maintaining signal integrity and minimizing distortion. In contrast, a high output impedance can lead to signal loss and reduced performance when driving loads.

An amplifier is both an input and output device. An amplifier, as its name suggests, amplifies a signal, meaning that it makes it stronger. An amplifier takes something as input, like maybe a sound signal, and its output is a more powerful (or louder) version of the same signal.
Answer is GAIN
Reduce the distortion in output signal.
A: The signal output will not change it is just that the efficiency of power transfer is effected to less

A: If the input is zero the desire output is zero no matter what class it is.
