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.

Are amplifiers input or output devices?

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.


What is the ratio of the output signal to the input signal of an amplifier that is usually measured in decibels?

Answer is GAIN


What is use of negative feedback in amplifier?

Reduce the distortion in output signal.


Why is the output signal affected if the impedance of the amplifier and the load do not match?

A: The signal output will not change it is just that the efficiency of power transfer is effected to less


Which amplifier uses the base as the reference terminal for the input and output signal?

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.

What is meant by an output impedance of 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.
