If a signal has infinite values within a finite range, what type of signal is it typically classified as?

A signal that has infinite values within a finite range is classified as an analog signal. This is because analog signals represent information in a continuous manner, meaning that the signal can take any value within a specified range. They are characterized by their smooth and uninterrupted waveform, which allows them to closely follow the information they represent.

In contrast, digital signals are composed of discrete values, typically represented in binary form, which only allow for specific levels rather than an infinite range of values. The other options, such as power signal and information signal, do not specifically describe the nature of the signal's value continuity. A power signal pertains to the ability of the signal to convey power over time, while an information signal refers to signals that carry information, which can be either analog or digital in nature.

Thus, the nature of having infinite possible values within a finite range is a definitive characteristic of analog signals, making this classification accurate.
