A phasor is a complex number that
represents the amplitude and phase angle of
a sinusoidal function.
It transforms a sinusoidal function from time
domain to the complex number domain
The IEEE Dictionary (IEEE 100) defines a
phasor as ‘‘a complex number.’’
Phasors are credited to electrical engineer
Charles Proteus Steinmetz (1865–1923)
