Hello everyone.
Iam about to read a course in DSP and I can't get my head why complex exponentials are used as input signals that often?
Is it just to simplify the math?
If not, what exactly is the imaginary part of a complex exponential? Does it "do" anything special compared to a real valued sinusoidal (rotation?)?
Most of the times you just compute Magnitude and Phase with the help of the real and imaginary part, but what is it that is so special about these types of input signals?
Any help would be great!
Thanks in advance,
(Very confused) Mike
