Question
The open-loop DC gain of a unity negative feedback system with closed loop transfer function is ____Select one:a. 4b. 4/13c. 4/9d. 9
Solution
To find the open-loop DC gain of a unity negative feedback system with a closed-loop transfer function, we need to evaluate the value of the transfer function at DC (zero frequency).
The open-loop transfer function is given as H(s) = 4/(s+1)(s+3). To find the DC gain, we substitute s with 0 in the transfer function.
H(0) = 4/(0+1)(0+3) = 4/1*3 = 4/3.
Therefore, the open-loop DC gain of the system is 4/3.
The correct answer is not provided in the options given.
