Graphically, the independent variable is represented by horizontal axis or x-axis. And the dependent variable is represented by vertical axisor y-axis. Mathematically, a signal is a function of one or more than one independent variables.
It depends on a single independent variable. It either varies linearly or non-linearly depending on the expression of the signal. Examples of single variable signal are: S(x) = x+5 S(x) = x2+5 Where xis the variable S(t) = cos(wt+ϴ) Where tis the variable
A two-variable signalvaries with the change in the two independent variables. Example of a two-variable signal is S(x,y) = 2x+ 5y 1. Related Post: What is Quantization & Sampling? Types & Laws of Compression
A signal is defined by its characteristics. It shows the nature of the signal. These characteristics are given below:
The size of a signal is a number that shows the strength or largeness of that signal. As we know, a signal’s amplitude varies with respect to time. Because of this variation, we cannot say that its amplitude can be its size. To measure the signal size, we have to take into account the area coveredby the amplitude of the signal within the time durat...
Signals are classified into different categories based on their characteristics. Some of these categories are given below.
