Introduction to Signals - Carnegie Mellon University
WebIt is possible to derive one signal from another simply through mathematical manipulation. Remember in continuous-time; $u (t)$ and $\delta (t)$. $\delta (t) = \frac {du (t)} {dt}$. $u (t) = \int_ {-\infty}^ {t} \delta (\tau) d\tau$. In discrete-time: $u [n]$ and $\delta [n]$. So $\delta [n] = u [n] - u [n-1]$.
