Let us assume that the function f(t) is a piecewise continuous function, then f(t) is defined using the Laplace transform. The Laplace transform of a function is represented by L{f(t)} or F(s). Laplace transform helps to solve the differential equations, where it reduces the differential equation into an algebraic problem. The three main properties that you need to be aware of are shown below. Property 1: The Dirac delta function, δ ( x – x 0) is equal to zero when x is not equal to x 0. δ ( x – x 0) = 0, when x ≠ x 0. Another way to interpret this is that when x is equal to x 0, the Dirac delta function will return an infinite value. δ ( x – x 0 ...Laplace Transforms of Periodic Functions. logo1 Transforms and New Formulas An Example Double Check Visualization Periodic Functions 1.
