Let x(t) = Aejwt + Be jwt where A and B are complex numbers expressed in polar form A = B = riejo rzejd Is x (t) a power or energy signal? If it is an energy signal, compute its energy. If it is a power signal, compute its power. (Hint: Use the fact that the square magnitude of a complex number v is: |v|2 = v*v, where v* is the complex conjugate of the complex number v.) Hint: what function is "delta-like"? (b) (5 points) Is x(t) = e−(2+jw₁+jw₂)tu(t + 3) an energy signal or power signal? Again, if it is an energy signal, compute its energy. If it is a power signal, compute its power. o(at) = 70(1) a Let x(t) = Aejwt + Be jwt where A and B are complex numbers expressed in polar form A = B = riejo rzejd Is x (t) a power or energy signal?
