Analog electronics

The components used in electronic circuits may be classified into two categories namely active and passive compo+nents. Active components are those which can perform signal processing functions such as signal generation, rectification and amplification. These components basically are semiconductor diodes, transistors and SCR’s etc. Batteries and generators which supply energy, also fall in the category of active components. The passive components are those which can not by themselves perform the above mentioned functions. The basic passive components are resistors, inductors and capacitors. In this chapter the analysis of electric circuits or networks, consisting of d.c. sources as the source of energy and other elements like resistors will be discussed using different methods. In addition different theorems will also be discussed to analyze complicated networks.

 Before discussing the methods of analysis of network, it is necessary to give the model of the battery or the generator which supply energy to the network.
