If the function is already shifted by some other value n 1 then the total shift is n 0 + n 1. So the equivalency that you're trying to prove doesn't exist. – Matt L.

WebMay 22, 2024 · The sifting property of the discrete time impulse function tells us that the input signal to a system can be represented as a sum of scaled and shifted unit impulses. Thus, by linearity, it would seem reasonable to compute of the output signal as the sum of scaled and shifted unit impulse responses. 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) \$.
