Hi, Laplace transforms are a fundamental tool in electrical engineering and control systems engineering. Unfortunately my University is having us read books that use Laplace Transforms, but I've never learned the theory rigorously! For example the book I'm currently reading state briefly that "A multiplication in the complex domain is a convolution in the time domain, thus Y(s) = G(s)X(s) = ... etc.". I'm a curious person and I would much rather learn the theory of Laplace Transforms in a semi-rigorous way. Does anyone have a great website or book to recommend? I know I cannot get into the intricate details like a pure mathematician would, but it would be nice to learn more about this since I feel like I have been given a power tool without the proper training to use it. Thanks in advance!
