🔍 Key Concepts

• Difference between digital and analog signals in electronics • Meaning of common converter acronyms like ADC and DAC • Direction of conversion: digital → analog vs analog → digital

💭 Think About

• Which device is used when you want a smooth, continuously varying output (like a volume control voltage) from a digital source such as a microcontroller? • Look at each acronym: which letters stand for "Digital" and which stand for "Analog," and what order are they in? • For each choice, ask yourself: does this device normally take an analog input or a digital input?

✅ Before You Answer

• Identify which option’s name clearly indicates digital-to-analog conversion • Eliminate any option that is commonly known for analog-to-digital conversion instead • Check that the acronym you select is a standard, widely used term in basic electronics (not something rarely seen or unclear).
