(a) ( 7 points) Consider an I.Tl (linear time-invariant) system whose response to
x_(2)(f)is
n(t), where
r_(1)(t)and
n(t)are illedrated as followin: Sirtch the response of the system to the imput
r_(2)(t). (b) ( 6 points) Assume we have a linest vostem with the Shallowitg ingrat-out pat pairx the contpat is
n(t)=cos(t)u(t)when the inpot is
x_(1)(t)=m(t)f the couput is
y(t)=cos(t)(u(t 1)-u(t))whom the imput is
x_(2)(t)=sect(t (1)/(2)). Is the system time-invariant?
