All the circuits that we have analyzed are linear circuits and we must be more specific in defining a linear circuit. We can consider the most important consequence of linearity, the principle of ...

In this tutorial, we will show that by writing the Fourier series expansion of a periodic signal in an intuitively obvious form, it is possible to interpret Parseval’s equality energetically. In this ...

When dealing with more than one input, the superposition theorem occupies the top of the list as its extension naturally leads to the Extra Element Theorem (EET). By first introducing superposition ...

Abstract: The superposition theorem (ST) and the substitution theorem are two important theorems in circuit theory. By principle, ST can only be used in linear circuits, while nonlinear circuits are ...
