An electronic signal contains some information which cannot be utilized if doesn’t have proper strength. The process of increasing the signal strength is called as Amplification. Almost all electronic equipment must include some means for amplifying the signals. We find the use of amplifiers in medical devices, scientific equipment, automation, military tools, communication devices, and even in household equipment.

In this tutorial, we will discuss all the important concepts from the introduction of transistors along with the amplifier action of transistor. In addition, we will cover all the topics related to all the major types of transistor amplifiers in detail.

Audience

This tutorial will suit all beginners who want to learn the fundamental concepts of transistors and transistor amplifier circuits.
