The function of a transducer is to _______________ ?
Correct answer: C. Convert the primary signal into a more useful quantity, usually an electric impulse
- A. Modify the input signal
- B. Amplify the input signal
- C. Convert the primary signal into a more useful quantity, usually an electric impulse
- D. Codify/decodify the input signal
Explanation
A transducer converts a measured physical quantity or primary signal into another usable form, commonly an electrical signal for transmission, indication, or control. Amplification and signal coding may follow, but they are not its basic function.
