OWY 1.13) Let $x(t) = \delta(t+2)-\delta(t-2)$. Find the energy of $y(t) = \int_{-\infty}^t x(\tau) d \tau$.

OWY 1.16) Let $y[n]=x[n] x[n-2]$.

- a) Is the system memoryless?
- b) Determine the output of the system when the input is $A \delta[n]$, where $A$ is any real or complex number
- c) Is the system invertible
