Obtain the input impulse response h(t) and the system function H(s) of your system

A very simple system:

$ y(t)=x(t)\, $ and $ x(t)=\delta(t) $

We can get $ h(t)=\delta(t)\, $

$ y(t) = \int^{\infty}_{-\infty} \delta(t) dt\, $

$ H(s)=\int_{-\infty}^{\infty}h(\tau)e^{-s\tau}d\tau $

$ H(s)=\int_{-\infty}^{\infty}u(\tau)e^{-s\tau}d\tau $

$ H(s)=\int_{0}^{\infty}e^{-s\tau}d\tau $

$ H(s)=-se^{-s\tau}|_0^\infty \, $

$ H(s)=-s(e^{-\infty} - e^{0})\, $

$ H(s)=s\, $

Compute the response of your system to the signal you defined in Question 1 using H(s) and the Fourier series coefficients of your signal

Signal defined in Question 1: $ X(t) = 6\cos(2\pi t) + 8\sin(4\pi t)\, $
