Analog and Digital signals are the types of signals carrying information. The major difference between both signals is that the analog signals that have a continuous electrical, while digital signals non-continuous electrical. The difference between analog and digital signal can be observed with the various examples of different waves.
The 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 been declined with the arrival of digital signals. In short, to understand the analog signals – all signals that are natural or comes naturally are analog 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 Signal
The Difference between Analog and Digital Signal in tabular form is given below.
|Difference Between Analog And Digital Signal|
|Analog Signals||Digital Signals|
|Continuous signals||Discrete signals|
|Represented by sine waves||Represented by square waves|
|Human voice, natural sound, analog electronic devices are few examples||Computers, optical drives, and other electronic devices|
|Continuous range of values||Discontinuous values|
|Records sound waves as they are||Converts into a binary waveform.|
|Only be used in analog devices.||Suited for digital electronics like computers, mobiles and more.|
Both these signals are used in electronic communication system to transfer information from one place to another.
