Assume that you are dealing with a one-degree-of-freedom system which follows the equation: x 20x 20x=u0cos(t), where x=x(t) is the generalized coordinate of the oscillator at time t , and the parameters , 0 , u0 , and are known to you (we will give them specific values later). Furthermore, assume that you are making noisy observations of the absolute acceleration at discrete timesteps t (also known)
