Extracted text: (a) Signals x1(t) = 10* rect (10*t) and x2(t)= 8(t) are applied at the inputs of the ideal filters Hi (o) = rect (o/40,000T) and H2() = rect (o/20,000r) 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) V:(t) H1(w) y(t) = y:(t).y2(t) x2(t) y2(t) H2(w) Figure 3(a) i. Sketch X1(@) and X2(@). ii.
