    getchar() in C language URGENT

    Normally while reading a text file we use a loop command while((c=getchar()) != EOF) and when it reaches the EOF the loop breaks. Question : Is there any way that we can jump the control again to the beginning of the text file so that c=getchar() begins again???

    Input IMPEDANCE of Large and small signal models

    Is input impedance same for both large signal and small signal models. My friends say that they are different, but I didn't get it. I think that they are the same for both the models. My theory: While calculating the input resistance in the lab, small signal model, we usually divide the voltage...

    Transistor vs diode.

    Hello Everyone, I am getting confused with transistor and diode stuff. in the active region the characteristics of a transistor i.e acting as voltage controlled current source it resembles a diode. Even the equations are same including the small signal model equations. Ic=Is*exp(Vd/Vt) and...
