Phasor Analysis: Factoring a Complex Sinusoid into Phasor Times Carrier

The heart of the preceding proof was the algebraic manipulation

For an arbitrary sinusoid having amplitude , phase , and radian frequency , we have

re

Thus, a sinusoid is determined by its frequency (which
specifies the carrier term) and its phasor
,
a complex constant. Phasor analysis is pursued further in
