What device converts analog output signal into numeric data based on the binary number system of 0 and 1?

• A. Analog to Digital Converter (ADC)
• B. Analog Data
• C. Artifact
• D. Attenuation

Answer: (A)

The device that turns an analog output into numeric data using binary 0 and 1 is the Analog to Digital Converter. It works by sampling the continuous signal at regular intervals, determining the signal’s amplitude at each sample (quantization), and then encoding that amplitude as a binary value. The sequence of binary numbers produced represents the original analog signal in a form that computers can store, process, and display.

In dental radiology, sensors or detectors generate small, continuous electrical signals proportional to the X-ray exposure. An ADC digitizes these signals so the imaging system can perform processing, enhance images, and store them digitally.

Other terms from the options don’t perform conversion to digital data: Analog Data describes non-digital information, artifacts are unwanted image features, and attenuation describes the weakening of the X-ray beam as it passes through matter.
