To keep things basic, the LaPlace and Fourier transforms are similar. I believe phasors fall under LaPlace, but I am not sure. Readingthis on pg. 1 the LaPlace transform is "a superset of the phasor representation..."

Both have a real and imaginary part denoted by sigma and j omega, and I think I understand this. I will only ask a few questions because I have read so much that I will probably ask contradicting questions. For now I would like to know the following:

- The LaPlace operator 's' is equal to sigma + j omega and sigma is zero. Meaning that we are only interested in the imaginary part in the complex domain or S-Plane.

- Phasors also have a real and imaginary part. When these are expressed on 2-D cartesian graph: real (x-axis) and imaginary (y-axis). This is not the S-Plane.

- Fourier transforms take the magnitude and phase of a transfer function. A signal is broken into its separate spectral components and phase. Like an FFT.

All true or not true? Apologies of these contradict each other. Too much reading.
