Rectangular Form

The format for the rectangular form is

C = ± A ± jB

The effect of a negative sign.

Example 2.1: Sketch the following complex numbers in the complex plane:

a.      C = 3 + j 4

b.     C = 0 – j 6

c.      C = -10 – j 20

Solutions:

a.      See Fig. 2.3

2.1            Polar Form

The format for the polar form is

C = C

Where C indicates magnitude only and q is always meas­ured counterclockwise (CCW) from the positive real axis,

A negative sign has the effect shown in Fig. 2.7:

-C = -C  = C ± p

2.1            Conversion between Forms

The two forms are related by the following equations.
