Reminder on complex numbers

Form of a complex number

A complex number I can be written in different forms:

  • in Cartesian form:

    I = Ir + j Ii

    where:

    Ir : real part of I

    Ii : imaginary part of I

    j: pure imaginary number with j² = –1

  • in Polar form (or exponential form):

    I = I m o d   e j ϕ

    where:

    I mod : modulus of I

    ϕ : argument of I (or phase)

    j: pure imaginary number with j² = –1

Conjugate of a complex number

The conjugate of I is defined by:

I* = Ir – j Ii

Modulus of a complex number

The modulus of I is defined by:
