the inverse x(t) is found by determining first the inverse of each term Nk(s)/Dk(s) and then using the time-shift property to obtain the inverse of each term Nk(s)e−ρks/Dk(s). Exponentials in the denominator—Two cases: (a) Given the Laplace transform X(s)=N(s)D(s)(1...

If multiplication were a lot harder than addition, this could be very valuable. The idea of solving differential equations using the Laplace transform is very similar. We first transform to the s domain using the Laplace transform. That gets rid of all the derivatives, so solving becomes easy...

As stated in the preface, one of our strong motivations for writing this book is given by the historical success of the numerical and real inversion formulas of the Laplace transform which is a famous typical ill-posed and very difficult problem. In this chapter, we will see their mathematical...
