What is the strength of a delta function.

  1. Jun 1, 2012 #1
    Hi all,

    I read the following:

    "If g(t) starts with a delta function of strength Y/2, then...."

    I wonder what that means. Does it mean g(t) = 0.5Yδ(t) ?

    Yes. It means that

    [tex]\int_{-\infty}^{+\infty} g(t)dt=\frac{Y}{2}[/tex]

    So it coincides with [itex]\frac{Y}{2}\delta (t)[/itex].
