Signals gl(t) = 20000rect(20000t) and g2(t) = 8(t) are applied to the input of ideal low pass filters H1(w) = rect(w/80000z) and HI(w) rect(w/80000z) as shown in the following figure. The output of both filters is multiplied to obtain output y(t). 8,(1) 8₂ (0) (1) y(t)=x (1)y, (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). Determine the maximum bandwidth of the signal that can be transmitted through RC low pass filter with R-1000 ohm and C= 10° F, if over this bandwidth the amplitude response variation is to be 5% and time delay variation is to be 2%.
