Laplace Transform of Step Function The unit step function is defined as,u(t)={1 for t≥0 0 for t<0u(t)={1 for t≥0 0 for t<0Therefore, by the definition of the Laplace transform, we get,X(s)=L[u(t)]=∫∞0u(t)e−stdtX(s)=L[u(t)]=∫0∞u(t)e−stdt⇒...

It is first introduced here as an exact analytical method for finding the response of a single-DOF system. However, first we must define the unit impulse function. The unit impulse function If a force, F, acts on a mass, m, for time δt, we know from Newton's second law that the ...
