Readable Markdown	Word forms: (regular plural) Laplace transforms noun (Electrical engineering: Communication, Analog) The Laplace transform is named for French [mathematician](https://www.collinsdictionary.com/us/dictionary/english/mathematician "Definition of mathematician") Pierre-Simon Laplace (1749-1827). Like the Fourier transform, the Laplace transform is used for solving differential and integral equations. Laplace transform turns integral equations and differential equations to polynomial equations, which are much easier to solve. The Laplace transform is a powerful tool formulated to solve a wide variety of initial-value problems. Collins COBUILD Key Words for Electrical Engineering. Copyright © HarperCollins Publishers
