Extracted text: (a) Signals x1(t) = 10ª rect (10*t) and x2(t)= 8(t) are applied at the inputs of the ideal filters H1 (0) = rect (@/40,000t) and H2(@) = rect (/20,000rt) as in Figure 3(a). The outputs yı(t) and y2(t) of these filters are multiplied to obtain y(t) = y1(t).y2(t) x1(t) y:(t) H;(w) y(t) = y:(t).y2(t) x2(t) y2(t) H2(w) Figure 3(a) i. Sketch X1(@) and X2(@). ii. Sketch H1(®) and H2(@). ii. Sketch Y1(@) and Y2(@). iv. Identify the bandwidths of y1(t), y2(t) and y(t).
