The Laplace transform of the Dirac delta function is easily found by integration using the definition of the delta function: L{?(t?c)}=??0e?st?(t?c)dt=e?cs.- The function ?(x) has the value zero everywhere except at x = 0, where its value is infinitely large and is such that its total integral is 1. This function is very useful as an approximation for a tall narrow spike function, namely an impulse.
