Sifting property of dirac delta function

WebThe Dirac delta function, in contrast, has a simple Fourier transform, and the effect of multiplying a signal by a train of Dirac impulses is easy to show due to its sifting property. *: As an example, if you're going to be mathematically precise, you would say that the Dirac delta isn't a function at all, but a distribution instead. WebJun 2, 2016 · Let's say you are considering δ: S ( R) → R as a tempered distribution on the Schwartz class S ( R). Then ( ∗) means nothing but the definition of δ : δ ( f) = f ( 0) f ∈ S ( R). In this setting, ∫ 0 + ∞ d t f ( t) δ ( t) is not even a well-define notation. Your question is a nice example demonstrating that it could be dangerous ...
