A signal is defined as any physical or virtual quantity that varies with time or space or any other independent variable or variables. Graphically, the independent variable is represented by horizontal axis or x-axis. And the dependent variable is represented by vertical axis or y-axis.

Explore the odd-even decomposition of any signal and the properties of periodic signals.
Signals can be categorized in various ways. The most common [verification needed] distinction is between discrete and continuous spaces that the functions are defined over, for example, discrete and continuous-time domains. Discrete-time signals are often referred to as time series in other fields.
Learn about signals and systems, two concepts that convey information and how it affects things. Explore types of signals, such as step, impulse, ramp, parabolic, and sinusoidal, and their properties and applications.
Learn about the four basic types of signals based on their time and amplitude variations, and how to calculate their parameters such as amplitude, frequency, phase, and root-mean square value. See examples of periodic and sinusoidal signals, and how to measure their signal to noise ratio.
