Webb22 maj 2024 · Rice University With the Laplace transform (Section 11.1), the s-plane represents a set of signals (complex exponentials (Section 1.8)). For any given LTI (Section 2.1) system, some of these signals may cause the output of the system to converge, while others cause the output to diverge ("blow up"). WebbLaplace transform converts a time domain function to s-domain function by integration from zero to infinity of the time domain function, multiplied by e-st. The Laplace transform is used to quickly find solutions for differential equations and integrals. Derivation in the time domain is transformed to multiplication by s in the s-domain.
