A signal is defined as $x(t) = 3(u(t) - u(t - 10))$. a. Determine the energy of the signal. b. Write a Matlab expression to define x(t) as an anonymous function. (Again, see section 1.11-1.) c. Using Matlab, define t = -1:0.1:20; E = sum((x(t)).^2)*0.1 How does E compare to the value found in part a? Why aren't they the same? d. How could you improve the match between E and the energy found in part a?
