a laplace transform exists when
Existence of Laplace transform
The Laplace transform L[f(x)] exists provided the integral ∫ ∞ 0 f(x)e−px dx f(x)e−px dx converges absolutely and the Laplace transform L[f(x)] exists |
How do you know if Laplace transform exists?
According to Schaum's "Laplace transform": The Laplace transform of f(t) is said to exist if the integral converges for some value of s; otherwise it does not exist.
The Laplace transform is defined for all values of s for which the integral exists.
This imposes restrictions on the type of function for which its Laplace transform exists.
Does Laplace transform always exist?
No, for a function to have a Laplace transform it is necessary for the integral which defines a Laplace transform to exist.
The integral does not exist for f(x) = 1/x because of the singularity at x =0.
The integral does not exist for f(x) = exp(x^2) because the function grows too quickly as x becomes large.
What is the condition for Laplace transform to exist?
The function f(x) is said to have exponential order if there exist constants M, c, and n such that f(x) ≤ Mecx for all x ≥ n. f(x)e−px dx converges absolutely and the Laplace transform L[f(x)] exists.
