Which of the following statements about analogue inputs is true?

The statement that analogue inputs can take on any value within a range is true. Analogue signals are continuous and can represent a wide variety of values, meaning they can vary fluidly within a specific range rather than being limited to discrete values. For example, temperature and voltage are typical analogue inputs that do not exist in fixed increments—they can be any value within the limits of their measurement capabilities. This continuous nature of analogue inputs allows for more nuanced representation of information compared to digital inputs, which have distinct values typically represented in binary (0s and 1s).

Analogue signals are often used in contexts where capturing variable information is critical, such as audio signals or sensor readings. This ability to represent a spectrum of values within a range is a defining characteristic of analogue inputs.
