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) \\). WebJul 23, 2024 · A novel spherical convolution is defined through the sifting property of the Dirac delta on the sphere.
