Analog signals can take an infinite number of values. Which statement is true?

• A. Infinite
• B. Finite
• C. Discrete
• D. Boolean

Answer: (A)

Analog signals are continuous in amplitude, meaning they can assume any value within a range. Because of that continuity, there are infinitely many distinct values the signal could take between any two points. Finite would contradict this by implying only a limited set of values. Discrete describes signals that step between fixed levels, not a smooth continuum, which isn’t characteristic of analog signals. Boolean restricts to two values, a digital property, not applicable to analog. So the true statement is that analog signals can take an infinite number of values.
