Mathematically, a signal is represented as a function of an independent variable t. Most of the time t stand for time. The mathematical notation of a signal is x(t).

What is the representation of signal?
Signals can also be represented by a magnitude and phase as a function of frequency. Signals that repeat periodically in time are represented by a power spectrum as illustrated in Figure 2.
How do you represent a signal in an equation?
A signal is periodic if it satisfies the equation f ( t ) = f ( t + T ) f(t) = f(t + T) f(t)=f(t+T), where T T T is the fundamental time period.
How math is used in signal processing?
Mathematics and physics of the underlying processes need to be understood, modelled, and finally controlled. To be able to perform these tasks, some knowledge of trigonometric functions, complex numbers, complex analysis, linear algebra, and statistical methods is required.
Are signals and systems math?
As many a student will agree, the subject of signals and systems is one with a reliance on tools from many areas of mathematics. However, much of this mathematics is not revealed to undergraduates, and necessarily so.
