Let us start with the definition of the convolution. y ( t) = ∫ e − τ u ( τ) ∑ k = − ∞ ∞ δ ( t − 2 k − τ) d τ. Then we use the sifting property to obtain. y ( t) = ∑ k = − ∞ ∞ e 2 k − t u ( t − 2 k). Now the summation over k should include the integers that are smaller than 2. chinese csgo callouts https://24shadylane.com

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).

WebIn other words: As you wrote in your initial post, the result of the convolution of δ ( ⋅ + t 0) and δ ( ⋅ − t 0) cannot be computed by standard means as a function. So, we will try to see how it acts unter integration, it's like δ is defined by the property. ∫ R δ ( t) ϕ ( t) d t = ϕ ( 0) for smooth functions ϕ.
