Q. What is the algebraic sum of the reference input and feedback?

  • (A) error signal
  • (B) error detector
  • (C) controlled system
  • (D) controlled output

✅ Correct Answer: (A) error signal
Explanation: in the block diagram of a basic control system we see that the reference input is passed through error detector or comparator. the signal which leaves the same is the algebraic sum of reference input and feedback as the feedback wire is connected to the detector, so we call it error
