2.9 Using the definition of power-type and energy-type signals 1. Show that x(n) = 8(0.5)n u(n) is an energy-type signal and find its energy content. 2. Show that x(1) = (sin7/2t)² , 0 < t < 2 is a power-type signal and find its power content. 3. Show that the raised cosine pulse (cos wt + 1) x(t) = else has an energy of 31 /44 J.
