Control Systems For a transfer function H (s) = P(s) / Q(s), where P (s) and Q (s) are polynomials in s. Then the degree of P (s) is always greater than the degree of Q (s). the degree of P (s) and Q (s) are same. maximum degree of P (s) and Q (s) differ at most by one. degree of P (s) is independent of degree of Q (s). the degree of P (s) is always greater than the degree of Q (s). the degree of P (s) and Q (s) are same. maximum degree of P (s) and Q (s) differ at most by one. degree of P (s) is independent of degree of Q (s).

Control Systems The input-output relationship of a linear time invariant continuous time system is given by r(t) = d²c(t)/dt² + 3 dc(t)/dt + 2 c(t) Where r(t) and c(t) are input and output respectively. What is the transfer function of the system equal to? 2/(s² + s + 2) 1/(s² + 3s + 2) 1/(s² + s + 2) 2/(s² + 3s + 2) 2/(s² + s + 2) 1/(s² + 3s + 2) 1/(s² + s + 2) 2/(s² + 3s + 2) ANSWER DOWNLOAD EXAMIANS APP
