Analog electronics

So far the analysis of networks containing only batteries and resistances has been discussed. In this chapter the network with time varying sources, resistances and other elements like inductances capacitances and transformers, etc. will also be discussed. The time varying sources are generally of three types, viz., periodic, aperiodic and random. Sine, Square and Triangular waves are periodic, since it repeats after a fixed interval of time. Periodic waves are generally used in the electronic circuits and are of our great interest. A pulse is aperiodic and noise is of random nature
