In the analog-to-digital converter path, which component stores the image data?

• A. Computer memory
• B. Video tape recorder
• C. Dielectric matrix
• D. None of the above

Answer: (C)

The idea is that an analog-to-digital conversion path needs a place to hold the sampled image values long enough to convert them and move them on for processing. A dielectric matrix serves as that temporary storage element, storing the image data as charges in a grid. This in-path storage lets each pixel’s signal be kept steady while it’s digitized, before it’s read out for processing or display.

Computer memory is used for storing data after processing or for long-term storage, not as the immediate in-path storage during conversion. A video tape recorder records video streams but isn’t the typical storage element inside the ADC chain. None of the above isn’t correct here because there is a dedicated in-path storage element—the dielectric matrix.
