Difference between Analog and Digital Signal

Analog and digital signals are the types of signals carrying information. The major difference between both signals is that the analog signals have continuous electrical signals, while digital signals have non-continuous electrical signals. The difference between analog and digital signal can be observed with the examples of different types of waves.

What Are Analog Signals?

Analog signals were used in many systems to produce signals to carry information. These signals are continuous in both values and time. The use of analog signals has declined with the arrival of digital signals. In short, to understand analog signals –  all signals that are natural or come naturally are analog signals.

What Are Digital Signals?

Unlike analog signals, digital signals are not continuous, but signals are discrete in value and time. These signals are represented by binary numbers and consist of different voltage values.

Difference between Analog and Digital Signals

To summarise, we have given the various differences between analog signal and digital signal in a tabular form below. Both these signals are used in electronic communication system to transfer information from one place to another.
