- 3. You have come to encounter an LTI system. You have no idea how the system behaves. So, you decide to drive the system with a particular input and measure the output. When you put the input u(t) = et 1(t), you find that the output y(t) = (1-e) 1(t). You can assume zero initial conditions. Now, find the transfer function of the system.arrow_forward1. Consider the following LTI system. d²y dy du +7 +6y= -- +2u, t≥0 dt² dt dt a) What is the impulse response of the system? Recall, h(t) = L-¹(H(s)). b) What are poles and zeros of the system? c) Suppose the initial condition of the system is y(0) = 1 and y'(0) = 4. What is the zero-input response of the system? d) Consider an input u(t) = (1 + et) 1(t) to the system. What is the zero-state response of the system for this input? e) Suppose, the initial condition was y(0) = -2 and y'(0) = -8 and the input is u(t)=(1+e) 1(t). What will be the total response of the system? You should be able to answer this using the linearity property of the system and your answers in part b and part c without taking any inverse Laplace transform.arrow_forwardGiven a normally distributed variable X with mean 4 and standard deviation 2, fi (a) P(X5).
