During digital image formation and processing, quantization takes place in which device?

Explanation:
Quantization is the step where a continuous signal from the detector is mapped to a finite set of discrete digital values. This happens when the analog signal is converted to digital form by an analog-to-digital converter. In digital radiography, the detector’s analog output (a range of voltages or light intensities) is sampled and then assigned to one of a fixed number of digital levels by the ADC, enabling storage and processing as digital data. The display monitor will later translate digital values back into visible light through a separate digital-to-analog conversion, but the actual quantization of the image signal occurs during the ADC stage. The other devices mentioned are not responsible for converting the analog image signal into digital codes.
