• HW #3 - Show graphically that $\underset{-\mathrm{\infty }}{\overset{\mathrm{\infty }}{\int }}{e}^{j2\pi f(t-u)}df=\delta (t-u)$ (Chris Lau)(Jodi S. Hodge)(Chris Wills)(Victor Shepherd)

• HW #4 - Given a linear time-invariant system where $u(t)$ produces an output $w(t)$, find the output due to any function $x(t)$ (Chris Lau)
• HW #5: (Chris Lau)
  • Part 1 - Find ${ℱ}[e^{-\sigma t}x(t)u(t)]$ and relate it to the Laplace Transform. Derive the Inverse Laplace Transform of this from the inverse Fourier Transform.
