An analog signal is one that is continuous in both instances of time and amplitude.

Now, in the real world examples of Analog signals are; current, voltage, temperature, pressure, light intensity etc.

Meanwhile, the digital signals are those that contain the digital values which are usually converted at specific instances from the analog signal.

This means that they can have only 2 states which is On or Off.
