What indicator circuit converts digital display data from the data processing circuits into analog drive signals?

• A. Deflection
• B. Amplifier
• C. Modulator
• D. Receiver

Answer: (A)

The indicator circuit that performs this conversion is the deflection circuit. It takes digital display data from the data processing circuits and converts it into analog voltages that drive the display mechanism, positioning the image on the screen (horizontal and vertical deflection for a CRT, or equivalent drive signals for other display types). This often involves digital-to-analog conversion and scaling to map digital values to the appropriate analog levels required by the display hardware.

Amplifiers simply boost signal amplitude, modulators mix signals with a carrier, and receivers handle incoming signals; none of these convert digital display data into the actual analog drive signals used to form the image.
