TRANSISTOR - Introduction

Introduction. Beside diodes, the most popular semiconductor devices is transistors. Eg: Bipolar Junction Transistor (BJT)Transistors are more complex and can be used in many waysMost important feature: can amplify signals and as switch Amplification can make weak signal strong (make sounds louder and signal levels greater), in general, provide function called Gain.
