So I am getting to grasps with Fourier transforms. Intuitively now I definately understand what it does and will soon follow some classes on the mathematics (so the actual subject). But then I go on reading about the laplace transform and there I kind of lose it. What is the moment of a signal? Why is the fourier transform a special case of the laplace transform? How can I come to grips with the Laplace transform?

Ive looked at these sources before I asked this question:

What is meant by a system's "impulse response" and "frequency response?"

How to distinguish between the different frequency domains?

Amplitude vs Frequency Response

Why is the Fourier transform so important?
