The
differences between v(t) and V:
•v(t) is instantaneous or time-domain
representation
V is the frequency or phasor-domain representation.
V is the frequency or phasor-domain representation.
•v(t) is time dependent, V is not.
•v(t) is always real with no complex term, V is generally complex.
Note: Phasor
analysis applies only when frequency is
constant; when it is
applied to two or more sinusoid signals only if they have the same frequency.
