What is the use of transistor as amplifier?

A transistor acts as an amplifier by raising the strength of a weak signal. The DC bias voltage applied to the emitter base junction, makes it remain in forward biased condition. This forward bias is maintained regardless of the polarity of the signal.

How does amplifier used in daily life?

An Amplifier or an operational amplifier (op-amp) circuit is commonly used in the automation, control and other electronic circuits for marine applications. The applied input signal is usually a voltage or a current signal. The purpose of an amplifier is to produce an output signal larger than that of the input signal.

Which transistor amplifier is commonly used?

In most of the electronic circuits, we use commonly NPN transistor configuration which is known as NPN transistor amplifier circuit. Let us consider a voltage divider biasing circuit which is commonly known as a single stage transistor amplifier circuit.

What are the uses of amplifier?

What Is an Amplifier? An electronic amplifier is a device that is used to increase the power, current, or voltage of a signal. Amplifiers are used in music equipment, electronic devices such as television and radio receivers, audio equipment, and computers to increase the amplitude of a signal.

What are uses of transistor?

Transistors are commonly used in digital circuits as electronic switches which can be either in an “on” or “off” state, both for high-power applications such as switched-mode power supplies and for low-power applications such as logic gates.

When transistor is used as an amplifier it increases amplitude?

Transistor as an amplifier—A device which increases the amplitude of the input signal is called amplifier. The weak input signal (i.e. a signal of small amplitude) is fed to the amplifier which is turns amplifiers it and we get output signal or large amplitude.

What are the uses of transistor in our daily life?

Uses Of Transistor. In our modern society, extensive use of electricity has enabled various uses of transistors in every electronic circuit. Transistors are used in our day to day lives in many forms which we are aware of as amplifiers and switching apparatus. As amplifiers, they are being used in various oscillators, modulators,

What are the applications of transistor as an amplifier?

Applications of Transistor as an Amplifier 1 It can be used in long-distance communication because the intensity of the signal obtained at the output will be high. 2 In the radio signals amplification, these transistor amplifiers are utilized. 3 The amplifiers play a prominent role in wireless communication.

What are the advantages of transtransistor working as an amplifier?

Transistor working as an amplifier has various advantages and applications in the field of electronics and communication. They are 1. It can be used in long-distance communication because the intensity of the signal obtained at the output will be high.

How does a transistor amplify a weak signal?

Overall, the weak signal is thus amplified in the collector circuit. However, to work as an amplifier, the transistor has to work in the active region of the output voltage versus input voltage curve as seen in the figure below.
