What is the difference between analog and digital signals?

Analog signals are characterized by their continuous nature, meaning they can take on any value within a given range. This allows them to represent an infinite number of points, making them ideal for capturing real-world phenomena such as sound, light, and temperature. For example, when you record a voice, the variations in sound waves are captured as continuous signals that vary over time, producing a smooth waveform.

In contrast, digital signals are discrete and represent data in binary format (0s and 1s). They are suited for digital devices because they simplify the processing and transmission of information while reducing noise and interference.

The continuous nature of analog signals allows for a more realistic representation of natural events than the discrete nature of digital signals. It is this ability to encompass a full range of values that distinguishes analog signals and makes option C the correct answer.
