Sine wave

Of the sinusoid (adjective sinusoidal ) is a sinusoidal function which is formed from the sine function by scaling the amplitude and frequency and phase shift. It forms the basis of representation in the frequency domain.

Definition

The sinusoid is defined by

In which

  • The scaling of the amplitude,
  • Scaling the angular frequency
  • The phase shift and
  • The absolute term

Is. In electrical engineering we mean by the absolute term of the time-constant DC component is

Cosine

As is true, a function of the shape of a sinusoid, the other trigonometric functions, however, is not as well.
