What are the differences between the Fourier and Laplace transforms and how do they each contribute to the analysis of signals and systems?
The Fourier transform is used to analyze signals in the frequency domain, showing the signal's frequency components. It is mainly used for periodic signals. The Laplace transform, on the other hand, is used for analyzing signals in the complex frequency domain, showing both frequency and decay rates.
