in the Laplace domain. In previous sections we have simply taken a system and observed the system's Fourier (i.e., frequency domain) transfer function. Although the frequency spectrum produced by a system elucidates much of the behavior of a system, it does not lend itself to physical modeling as it ignores any internal states within the system.This lecture introduces the most general definition of impedance in the Laplace domain.

Laplace Transform. The Laplace transform is a mathematical tool which is used to convert the differential equation in time domain into the algebraic equations in the frequency domain or s-domain. Mathematically, if $\mathrm{\mathit{x\left ( t \right )}}$ is a time domain function, then its Laplace transform is defined as −But the Laplace transform is usually used for stability analysis and control theory. And in those domains, the two-sided Laplace transform describes acausal systems -- systems that respond to a stimulus before that stimulus actually happens. This is nonphysical. So the one-sided transform is used instead:Also, the circuit itself may be converted into s-domain using Laplace transform and then the algebraic equations corresponding to the circuit can be written and solved.
