Question

consider a signal, y(t) defined as y(t)={(-t+2,0<=t<=1),(t-1,1<=t<=2),(-t/3+5/3,2<=t<=5),(0, otherwise) } the energy of the signal y(t) is E= 3J. A periodic signal Z(t) is defined as Z(t)={(y(t) for 0<=t<=6),(y(t+6) for all t)} The power of w(t)=1/2(Z(2t)) is ?​

Answer 1

Answer:

y(t) = [( - 2t ,o=244+75(8-8+(5)+45-(37)
