One 8 x 11 sheet of notes, and a calculator are allowed during the exam. Write all answers neatly and show your work to get full credit. Rationalize all complex fractions: (4 pts. each) clearly sketch each of the following signals (completely label the axes including all magnitudes and times of signals), x(t) = u(t)+u(t-1)-2u(t-2, x[n] = 5 knk : if x(t) = draw -2x(2-4t) x (t) 1 t: (5 points) prove whether the following functions are periodic and if so, determine their period (a) tx e j. 4: (10 points) we are given an lti system such that the response to the input x1(t) is the output y1(t) as shown below: x1(t) Clearly sketch (completely labeling the axes) the output y2(t) of the lti system corresponding to the input x2(t) shown below. Explain how/why you came up with the output you propose. x2(t)
