It is common terminology to call
the complex sinusoid's
its carrier wave.
For a real sinusoid,
the phasor is again defined as
and the carrier is
. However, in this case, the real sinusoid
is recovered from its complex-sinusoid counterpart by taking the real part:
The phasor magnitude
amplitude of the sinusoid.
The phasor angle
phase of the sinusoid.
When working with complex sinusoids, as in Eq. (4.11), the phasor
of a sinusoid can be thought of as simply the
complex amplitude of the sinusoid. I.e.,
it is the complex constant that multiplies the carrier term
