What is a System ?

A System is any physical set of components or a function of several devices that takes a signal in input, and produces a signal as output. These components interact with each other and with the environment to perform the function or process that will contribute to the system.

Introduction to Signals and Systems: Properties of systems

In this article, we will go through Signal and systems, First, we will define what is a signal and what is a system, then we will go through the calculation of the Energy and Power of Signals with their transformation, At last we will conclude our article with Properties, Applications and some FAQs.

Transformation of the Independent Variable

Shifting: the signal can be delayed ( x(t-T) ) or advanced ( x(t+T) ) by incrementing or decrementing the independent variable (time here). The shape of the graph remains same only shifted on the time axis.Scaling: the signal can be compressed ( x(at), a>1 ) or expanded ( x(t/a), a>1 or x(at), 1>a>0 ). Here the shape/behaviour of the graph of the signal changes as the fundamental time period changes. In compression the time period decreases and in expansion the time period increases.Reversal: also called folding as the graph is folded about the Y-axis or T if given x(T-t)....
