1 Quiz November th, Signals & Systems (--) Prof. R. D Andrea Quiz Exam Duration: Min Number of Problems: Number of Points: Permitted aids: Important: None Questions must be answered on the provided answer sheet; answers given in the booklet will not be considered. There exist multiple versions of the exam, where the order of the answers has been permuted randomly. Every question has a unique correct answer. Every question is worth one point for a correct answer, and zero points otherwise. Giving multiple answers to a question will invalidate the answer. No negative points will be given for incorrect answers. Partial points (Teilpunkte) will not be awarded. You do not need to justify your answers; your calculations will not be graded. Use only the provided paper for your calculations; additional paper is available from the supervisors. Good luck!

3 +//+ Discretization Box : Questions, A continuous-time LTI system G c is discretized using the exact discretization method for a zero-order hold input and a uniformly sampled output, such that G d = SG c H. This is done for a sampling time of T s = s and a sampling time of T s = s resulting in the discrete-time system G d, and G d,, respectively. Similarly, the continuous-time input u c is sampled with the two sampling periods T s = s and T s = s resulting in the two discrete time signals u d, and u d,, which are shown in the plot below.. u c u d, u d, Time (s) When the discrete-time input u d, = {...,,,,,,...} is applied to the discrete-time system G d, with state space description: q[n + ] = A d, q[n] + B d, u[n], y[n] = C d, q[n] + D d, u[n], its output is: y d, = {...,,,,,,...}. Question Given what are C d, and D d,? A d, = [ ] B d, = [ ], A C d, = [ ], D d, = [ ] [ C C d, = ], Dd, = [ ] B C d, = [ ], D d, = [ ] D C d, = [ ], D d, = [ ] Question What could be the output of the discrete time system G d,, which was obtained by discretizing G c using a sampling time of T s = s, when the input u d, = {...,,,,,,...} is applied to it? A y d, = {,,,,,...} B y d, = {,,,,,...} C y d, = {,.,,,,...} D y d, = {.,,,,,...} Question Assume you sample a continuous-time signal with the sampling rate f s = Hz.
