Given x1(t)=cos(t), x2(t)=sign(pt) and x3(t)=x1(t)+x2(t).
(a) Determine the fundamentals periods T1and T2 of signals x1(t) and x2(t).
(b) Show that x3(t) is not periodic, which requires T3=k1T1=k2T2 for some integer k1 and k2.
(c) Determine the powers Px1 , Px2 and Px3 of signals x1(t), x2(t) and x3(t).
