Question

question 9
the output of the measurement device is the ______.
○ measured variable
○ feedback signal
○ neither a or b

Explanation:

The measured variable is the physical quantity being detected by the device, not its output. A feedback signal is a signal sent back to a system's input, not the direct output of a measurement device. Thus, the output of a measurement device is neither of these.

Answer:

neither a or b
