Mathematical Definition: The Region of Convergence, or ROC, of a Z-Transform comprises all the values on the Z-plane for which the transformation converges. So, remember that: Z{x[n]} = + ∞ ∑ n = − ∞x[n]z − n. You should also keep in mind that z ∈ C, which means it can be written as: z = | z | ejθ.Calculate the Laplace transform. The calculator will try to find the Laplace transform of the given function. Recall that the Laplace transform of a function is F (s)=L (f (t))=\int_0^ {\infty} e^ {-st}f (t)dt F (s) = L(f (t)) = ∫ 0∞ e−stf (t)dt.
