Q7 / 100
What is the difference between "analog" and "digital" signals?
Correct! Well done.
Incorrect.
The correct answer is A) Analog signals vary continuously over a range of values; digital signals represent information as discrete values, typically binary (0s and 1s)
A
Correct Answer
Analog signals vary continuously over a range of values; digital signals represent information as discrete values, typically binary (0s and 1s)
Explanation
Analog signals (like a temperature reading from a sensor) vary smoothly, while digital signals use discrete levels (often two: high/low) — many embedded systems use ADCs to convert analog signals to digital for processing.
