The outputs of a digital transducer are in the form of:

• A. 1 to 5 mv.
• B. 4 to 20 ma.
• C. Digital computer words.
• D. On or off signals.

Answer: (C)

A digital transducer converts a physical quantity into a digital representation that a computer can process. Instead of just a single analog value, it outputs digital computer words—multi-bit binary data that encode the measurement with resolution and scale. This makes it directly usable by digital systems for processing, storage, and communication.

The analog-style outputs, like a voltage in millivolts or a current in milliamps, require further conversion to digital form before a computer can work with them. A simple on/off signal is just a single binary bit, which encodes only a crude yes/no state and isn’t sufficient to convey a measured value with meaningful precision.
