What is a Sinusoidal Wave Signal?

 Sinusoidal Wave Signal

A sine wave signal is defined as a periodic signal with smooth and repetitive oscillations based on a sine or cosine function.

Mathematical feature

It can be expressed as y (t) = A sin (ωt + φ), where A is the amplitude, ω is the angular frequency, and φ is the phase.

• y (t) is the signal value at time t

• A is the amplitude of the signal, i.e. the maximum deviation from zero

• f is the frequency of the signal, that is, the number of cycles per second

• ω= 2πf is the angular frequency of the signal, that is, the rate of change of the Angle, expressed in radians per second

• φ is the phase of the signal, that is, the initial Angle at time t= 0
