The Inverse Laplace Transform

howellkb.uah.edu

Linearity of the Inverse Transform The fact that the inverse Laplace transform is linear follows immediately from the linearity of the Laplace transform. To see that, let us consider L−1[αF(s)+βG(s)] where α and β are any two constants and F and G are any two functions for which inverse Laplace transforms exist.

Laplace transform for both sides of the given equation. For particular functions we use tables of the Laplace transforms and obtain sY(s) y(0) = 3 1 s 2 1 s2 From this equation we solve Y(s) y(0)s2 + 3s 2 s3 and invert it using the inverse Laplace transform and the same tables again and obtain t2 + 3t+ y(0)

If you know what a Laplace transform is, this should look like a discrete-time version of it, as indeed it is. ... Inverse Z-Transforms As long as x[n] is constrained to be causal (x[n] = 0 for n < 0), then the z-transform is invertible: There is only one x[n] having a given z-transform X(z). Inversion of the z-transform (getting x[n] back from ...

Differentiation and the Laplace Transform

howellkb.uah.edu

We will confirm that this is valid reasoning when we discuss the “inverse Laplace transform” in the next chapter. In general, it is fairly easy to find the Laplace transform of the solution to an initial-value problem involving a linear differential equation with constant coefficients and a ‘reasonable’ forcing function1. Simply take ...

Laplace Transform: Examples

math.stanford.edu

Inverse Laplace Transform: Existence Want: A notion of \inverse Laplace transform." That is, we would like to say that if F(s) = Lff(t)g, then f(t) = L1fF(s)g. Issue: How do we know that Leven has an inverse L1? Remember, not all operations have inverses. To see the problem: imagine that there are di erent functions f(t) and

is useful to have a name for the Laplace transform of the autocorrelation function; we shall refer to Sxx(s) as the complex PSD. Exactly parallel results apply for the DT case, leading to the conclusion that Sxx(ejΩ) is the power spectral density of x[n]. 10.2 EINSTEIN-WIENER-KHINCHIN THEOREM ON EXPECTED TIME AVERAGED POWER
