A zero-order instrument ideally produces an output that is?

  • AInstantaneously proportional to the input
  • BAlways delayed by one time constant
  • CAlways oscillatory
  • DIndependent of input
Report an error
Correct Answer: A. Instantaneously proportional to the input
Explanation: An ideal zero-order instrument has no dynamic energy-storage effect and follows the input proportionally without dynamic lag.
Reference: Standard measurements and instrumentation: dynamic characteristics
