..1l1t).B\ Question 1 (6 points) Periodicity (a) (3 pts) Find the period of the function x(t) = 7cos(5t + ~). (b) (3 pts) Sketch x(t). 4 I.E~E Carlet_on Question 2 (16 points) Block Diagram Representation 1 S 1 -1 x(t) S S+T y(t) (a) (9 points) Determine the transfer function of the system given by the block diagram shown in the above figure. (b) (2 points) Write the input-output differential equation corresponding to this system. (c) (5 points) For x(t) = u(t) with jj (0-) = -1, Y (0-) = 1, and y(O-) = 2, find Y(s) in terms of the natural and forced responses; that is, find Y(s) = Ynatural(S) + Yjorced(S). (Do not solve for the time domain expression y(t).) Question 3 (14 points) Convolution x(t) y(t) Z(t) nit * -!JLt = t -2 -1 - z(t) is the convolution of the two functions x(t) and y(t); that is, z(t) = x(t) * y(t). If x(t) and z(t) are as sho\\'n in the above figure, find y(t). Help:
