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.

WebAug 9, 2024 · This is simply an application of the sifting property of the delta function. We will investigate a case when one would use a single impulse. While a mass on a spring is undergoing simple harmonic motion, we hit it for an instant at time \(t = a\). In such a case, we could represent the force as a multiple of \(\delta(t − a) \\).
