Sinusoidal signal
A sine wave is a wave for which the amplitude depends on time, following a sine law. Its mathematical expression
is given by the following relation:
where :
represents the maximal magnitude, or the peak value of the sine wave.
represents the phase, in radians. It represents the initial angle of the wave at its origin.
is the angular frequency, and can be calculated with the period
of the wave with the relation:
.The frequency
of the sine wave is the inverse of the period
