Do each of the following eight (8) problems. The problems have equal weight. For each problem, in order to receive maximum possible credit, show the steps of the solution clearly,and provide appr...
2. (Chapter 2). A linear, time-invariant, continuous-time (LTIC) system with input f(t) and output y(t) is specified by the differential equation D2(D +1)y(t) (D - 3)f(t) Find the characteristic polynomial, characteristic equation, characteristic root(s), and characteristic mode(s) of this system. a. b. Is this system asymptotically stable, marginally stable, or unstable? Justify your answer. 2. (Chapter 2). A linear, time-invariant, continuous-time (LTIC) system with input f(t) and output y(t) is specified by the differential equation D2(D +1)y(t) (D - 3)f(t)...
2. (Chapter 2). A linear, time-invariant, continuous-time (LTIC) system with input 1(1) and output y(t) is specified by the differential equation D(D? + 1)y(t) = Df(t). a. Find the characteristic polynomial, characteristic equation, characteristic root(s), and characteristic mode(s) of this system. b. Is this system asymptotically stable, marginally stable, or unstable? Justify your answer.
1. (Chapter I). A continuous-time system, with time t in seconds (s), input f(t), and output y(), is specified by the equation y(t) 1.5cos(250t) +0.8f(t) a. Is this system instantaneous (memoryless) or dynamic (with memory)? Justify your answer b. Show that the system fails to satisfy the homogeneity or scaling property required for superposition to hold for inputs fi (0) = 2.0 and f(0) = 3 fi (0)-60. Clearly show and explain your work. 1. (Chapter I). A continuous-time system,...
2. Short-answer questions on various topics (20 marks total) In each case, clearly explain the reasoning behind your answer. a. (3 marks) A causal LTI system has an impulse response h[n], having an even component he[n] and an odd component ho[n]. The portion of he[n] for n > 0 is he[n] = 0.5(0.32)", n > 0. Determine the complete description of he[n], ho[n], and h[n]. b. (3 marks) A system has the transfer function z– 7z+6 H(2) = 22 -0.12...
