In this lab we introduce the fundamentals of LabVIEW. LabVIEW is
a programming environment that you will find helpful for many of
the exercises in this text.

Manipulating sinusoid functions using complex exponentials turns
trigonometric problems into simple arithmetic and algebra.
In this lab, we first review the complex exponential signal and the
phasor addition property needed for adding cosine waves.
Then we will use Matlab to make plots of phasor diagrams that show
the vector addition needed when combining sinusoids.
