Laplace Transform Method In subject area: Engineering The Laplace transform method is used to solve for the response of a dynamic system to discontinuous forcing functions and includes the initial conditions. F
The Laplace transform can be used to represent such delays. The Time-Delay theorem can be derived from the defining equation of the Laplace transform (Equation 6.4). Assume a function x(t) that is zero for negative time, but normally changes at t=0 sec. If this function is delayed from...

A method of measuring impedance is based on carrier function Laplace transform. The measurement includes detecting a response signal from a device under test, to which signal an excitation such as a p

Laplace transform methods are especially useful in solving problems that involve piecewise-defined, periodic, or impulse functions. Example 8.7.3 Solve x′=y=3δ(t−π)y′=−x+6δ(t−2π)x(0)=1,y(0)=−1. Solution We proceed in the exact same manner as in the previous ...
