In the figures below, the graph of f is given on the left, and the graph …Laplace transform to describe a bounded function. It is easy to show that if a real function f: R → R is contained in a strip [ a, b], that is if ∀ x a ≤ f ( x) ≤ b, then its Laplace transform is bouned by a s from below and b s from above. The inverse is, however, not true, as one can find unbounded functions that have bounded Laplace ...The Laplace transform will convert the equation from a differential equation in time to an algebraic (no derivatives) equation, where the new independent variable is the frequency. We can think of the Laplace transform as a black box that eats functions and spits out functions in a new variable. We write for the Laplace transform of .This lecture presents basic properties of Laplace transform needed to work with non-rational transfer matrices. The discrete time analog, z-transform, is also discussed. 9.1 Laplace Transform When studying Laplace transform, it would be very inconvenient to limit one’s attention to piecewise continuous functions only.This section uses the unit step function to solve constant coefficient equations with piecewise continuous forcing functions.
