Is the Dirac delta a function?
@dhamnekar What on earth are you talking about. The Dirac Delta is NOT a function. It is a distribution and it does not take on any value at any point. In this answer and this one, I provided primers on the Dirac Delta. Here, we present a simple heuristic way to evaluate the Laplace Transform of the Dirac Delta.
How to evaluate the Laplace transform of the Dirac delta?
Here, we present a simple heuristic way to evaluate the Laplace Transform of the Dirac Delta. We use the definition of the unit step function u(t) u ( t) for right-continuous functions as given by The function e−stu(t) e − s t u ( t) is not a suitable test function due to the discontinuity at t = 0 t = 0.
What is a Laplace transform Ode?
The Laplace transform technique becomes truly useful when solving odes with discontinuous or impulsive inhomogeneous terms, these terms commonly modeled using Heaviside or Dirac delta functions. We will discuss these functions in turn, as well as their Laplace transforms. Figure 5.3.1 5.3. 1: The Heaviside function.
