b) For the below system, fo = 150 Hz, f₁ = 100 Hz, and f₂ = 200 Hz. Note that x(t) and x2(t) are continuous time signals and h(t) is the impulse response of the LTI system. Answer the following questions. x₁(t) = cos(wot)e-j2mfit z₁(t) h(t)=sinc(f2t)e-12 (fo+f1) x2(t) = cos(wot)e/2xfit Z₂(t) h(t) = sinc(ft)e/2(fo+fi)t (i) Find the expression for z₁(t). (ii) Find the expression for z₂(t). (iii) Show that the output signal is given by y(t): cos(2π250t). 200 y(t)
