In mathematics, the Laplace transform, named after its inventor Pierre-Simon Laplace (/ l ə ˈ p l ɑː s /), is an integral transform that converts a function of a real variable t {\displaystyle t} (often time) to a function of a complex variable s {\displaystyle s} (complex frequency). s. x(t) t ­1 0 1 ­1 0 1 0 10. Laplace Transform (PDF) Advanced Engineering Mathematics Chapter 6 Laplace ... ... oaii Regions of convergence of Laplace Transforms Take Away The Laplace transform has many of the same properties as Fourier transforms but there are some important differences as well.
