(a) Compute the energy E infinity

y[n]=e^2+j4.71235n <n>$ lim $ from T to -T as T goes to infinity |y[n]|^2 |y[n]|^2= (e^2.e^jw)^2

       = e^4.1
       = e^4

using the E infinity formula from the textbook

=[e^4](T-(-T) =2e^4T =inf

(b) lim T->inf and integrate from -2 to 2 because of function delta(t+2)-delta(t-2) Use the same formula above.

=[e^4](2+2) =4e^4
