What is the derivative of the Dirac delta function?
The Dirac Delta function can be viewed as the derivative of the Heaviside unit step function H(t) as follows. The Dirac delta has the following sifting property for a continuous compactly supported function f(t). ?(t)e?i?tdt = 1.

What is the Laplace transform of the Dirac delta function?
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.
