Part A: Unit Impulse Response and System Function
$ h(t) = 9\delta(t) $
so:
$ y(t) = \int^{\infty}_{-\infty} h(\tau) x(\tau) d\tau $
$ y(t) = \int^{\infty}_{-\infty} 9\delta(\tau)e^{-j\omega_0(t - \tau)} d\tau $
$ y(t) = e^{j\omega_0 t} \int^{\infty}_{-\infty} 9\delta(\tau)e^{-j\omega_0 \tau} d\tau $
$ H(s) = 9e^{j\omega_0} $
$ H(s) = 9 $
Part B: Response of the System
$ x(t) = 1 + sin(8\pi t) + 2cos(8\pi t) + cos(16\pi t + \frac{\pi}{4}) $
$ x(t) = 1 + (\frac{e^{j8\pi t} - e^{-j8\pi t}}{2j}) + (e^{j8 \pi t} + e^{-j8 \pi t}) + (\frac{e^{j(16 \pi t + \frac{\pi}{4})} + e^{-j(16 \pi t + \frac{\pi}{4})}} {2}) $
So:
$ y(t) $
