D. r(t)
Answer:C
Which notation represents the feedback path in closed loop system representation?
A. b(t) B. c(t) C. e(t) D. r(t)
Explanation: Feedback can be positive and negative and feedback is so used to reduce the error of the system by comparing the final output with the desired output and reducing the error and this error is denoted with the symbol as e(t).
