Sinusoidal signal

A signal, which is continuous in nature is known as continuous signal. General format of a sinusoidal signal is

x(t)=Asin(ωt+ϕ)$$x(t)=A\sin (\omega t+\varphi )$$

Here,

A = amplitude of the signal

ω = Angular frequency of the signal (Measured in radians)

φ = Phase angle of the signal (Measured in radians)

The tendency of this signal is to repeat itself after certain period of time, thus is called periodic signal. The time period of signal is given as;

T=2πω$$T=\frac{2\pi }{\omega }$$

The diagrammatic view of sinusoidal signal is shown below.
