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. WebOct 4, 2024 · Here, is a correct derivation. 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. florists in beith

Typically a convolution is of the form: ( f ∗ g) ( t) = ∫ f ( τ) g ( t − τ) d τ. In your case, the function g ( t) = δ ( t − t 0). We then get. ( f ∗ g) ( t) = ∫ f ( τ) δ ( ( t − τ) − t 0) d τ = ∫ f ( τ) δ ( t − t 0 − τ) d τ. Using the fact that g ( t − τ) = δ ( ( t − τ) − t 0) Of course, the right ... greding positiv
