ELECTRONICS : the branch of engineering which deals with current conduction through a vacuum or gas or semiconductor is known as electronic. ANALOG SIGNAL: A continuously varying signal (voltage or current) is called an analog signal For example: sinusoidal voltage . Digital signal : A signal which can have only two discrete values is called a digital signal. For example a square wave is a digital signal. ...

Why bias a transistor ?

What is the importance of biasing ? 👇👇 transistor The purpose of dc biasing of a transistor is to obtain a certain dc collector current at a certain dc collector voltage. these values of current and voltage are expressed by the term operating point (quiescent point) . To obtain the operating point, we make use of some circuits; and these circuits are called "biasing circuits" .Of course , while fixing the operating point, it has to be seen that it provides proper dc conditions so that the specific function of the circuit is achieved. the suitability of an operating point for the specific application of the circuit should be seen on the transistor characteristics. for more post click ...
