Problem Set 4: Energy and Power Determination of two parameters such as energy and power from digital signal processing area is important in order to find out the signal strength. We know that every bounded periodic signal is power signal, since the signals do not converge to a finite value so their energy is infinite and their power is finite. Therefore, the signal is an energy signal if its energy is finite and power is zero. Besides, the signal is a power signal if its power is finite and its energy is infinite. Determine whether the given signal is energy signal or power signal x(n) = (0.25)"u(n) %3D

Graph theory

It is that part of network analysis where the configuration is called graph or structure of the network system when all of the elements (e.g., R, L, and C) in a network system are substituted with lines having circles/rings or dots across both endpoints. The study of the solution of the networks and circuits with the help of graphs is known as graph theory. The objective is to know the mathematics behind the network analysis.
