the input of ideal low pass filters H1(w) = rect(w/80000z) and H1(w) =

rect(w/80000n) as shown in the following figure. The output of both filters is

multiplied to obtain output y(t).

3(0)

B₂ (1)

y(t)=x{(1)x₂(1)

(a) Sketch G1(w) and G2(w). Label the graphs appropriately.

(b) Sketch H1(w) and H2(w). Label the graphs appropriately.

(c) Sketch Y1(w) and Y2(w).

(d) Find the bandwidth of yl(t), y2(t) and y(t).
