Sifting property proof
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) \\).

WebMay 22, 2024 · Time Shifting. Time shifting shows that a shift in time is equivalent to a linear phase shift in frequency. Since the frequency content depends only on the shape of a signal, which is unchanged in a time shift, then only the phase spectrum will be altered. This property is proven below: Example 9.4. 2.
