WebWhat is the sifting property? This is called the sifting property because the impulse function d (t-λ) sifts through the function f (t) and pulls out the value f (λ). Said another way, we replace the value of t in the function f (t) by the value of t that makes the argument of the impulse equal to 0 (in this case, t=λ).
