System
y(t)=7x(t)
Impulse Response
y(d(t))=7(d(t))
so the impulse response is 7d(t)
System function
H(s) = $ \int_{-\infty}^{\infty}7\delta(\tau)e^{-s\tau}d\tau $
$ H(s)=7 $
CT Input
$ x(t)=cos(3*pi*t)cos(6*pi*t)\! $
a2=6 a3=6 a9=6 a10=6
fundamental period = $ 2\pi/6 $
Response to Input
$ y(t)=42e^{2jt} + 42e^{3jt}+ 42e^{9jt}+ 42e^{10jt} $
