Introduction to Analog vs Digital Communication

Modern society in communicating does not need to meet face to face. The communication that people have makes it possible to transmit images, sounds, and videos via online. The word communication itself comes from the Latin “communicare”. Communication itself can also be interpreted as a process of sharing or exchanging information that usually connects individuals and systems. In the world of communication, there are also several kinds such as analog and digital communication. You need to know the difference between analog vs digital communication.

What Is Analog Communication?

Based on Physics and radio electronics, analog communication is the process of sending and receiving information that can take various forms. Examples of analog communication are voice, image, and video. The process of distributing information from this type of communication is done through analog signals. In the world of analog communication is also related to analog communication systems. The system consists of several elements that are combined together to build an analog communication bridge between fellow senders and recipients of the information.

What is Digital Communication?

In this analog vs digital article, we will also discuss the definition of digital communication. The definition of digital communication is the process of sending information that can be in the form of sound, images, and others through digital signals. Digital and analog signals are different things. The majority of modern technologies utilize digital communications, such as email, phone calls, SMS, video conferencing, and others.

What’s the Difference Between Analog Communication and Digital Communication?

When discussing the difference between digital and analog communication then the answer will be long. You can see some points of difference between the two types of communication as follows:

Analog CommunicationDigital Communication
Analog communication uses analog signals to convey information to the communicating individuals or systems.Digital communication utilizes digital signals to transmit information and digital signals are different from analog signals.
Analog communication also uses analog signals that are available in the form of sine waves.The process of transmitting information on digital communication through square waves.
Signals that are sent by analog communication are continuous and prone to interference with information transmission due to noise.The type of wave that this communication does is also in the form of discrete values.
The vulnerability of analog communication in conveying information due to noise also causes large errors.Digital communication will also not be easily influenced by noise so that it is immune from parallax errors.
In transmitting information, analog requires complex hardware.You can direct this digital communication by using hardware that is not complex.
Technological developments allow analog communication to take place more cheaply. It’s just that this communication must use low bandwidth.It is not surprising that digital communication can be accessed by the public at a more expensive price than analog communication.
This mode of communication mostly cannot be carried.This communication has the nature of being easy for people to carry anywhere, such as on a smartphone.

Why is Digital Communication Better than Analog?

In the future, there will be no more people using analog communication. All will switch to digital communication because it has many advantages. This time we will start discussing the many advantages of digital communication. You can find out the advantages of digital communication below:

1. Digital Communication is only immune from parallax errors because it is not affected by noise.

2. The hardware used to support this communication system is much more concise than analog communication so that the device size can be smaller.

3. Hardware for delivering information via digital communication is not as complex as analog communication.

4. Bandwidth for digital used in the form of high bandwidth.

5. Information can be delivered with less power.

6. Digital communication system is more portable than an analog communication system

Is Digital or Analog More Reliable?

Based on the discussion from the previous point, we can understand that digital is much more reliable. The information sent is also more protected from parallax errors because digital is not affected by noise. In addition, technology is more compact so it is more portable and people can take it to various places. The technology also only requires less power, so it is enough to just use the battery without having to charge it frequently. Even some countries have started to incorporate analog technology into museums and have begun to slowly phase out the production of analog communications.

What Is the Disadvantage of Digital Communication?

Although we already know that digital communication is more reliable than analog communication, this digital technology also has several weaknesses. The disadvantages of digital communication can be found in the following.

1. Still experiencing sampling error

2. Requires high bandwidth to be able to carry out its function as an introduction to information

3. Requires synchronization via synchronous modulation based on information from multiple websites

4. Technology users need to pay a higher price than analog technology users

What Is an Example of Digital Communication?

You are now wondering what is an example of a technology that utilizes digital communication. Some examples of technology are phones, email, social media, websites, apps, television, digital radio, streaming media, online games, digital documents, digital advertising, and so on. Modern human life absolutely cannot be separated from this digital communication.

Which Modulation System Is Digital?

In the world of digital communication, there is also the term Digital Modulation. Digital modulation itself means the process of coding the digital information signal into a certain phase, amplitude, or signal frequency. The encoding process will affect the bandwidth in a larger amount than analog.

Modulation techniques convert several bits of transmitted information into a symbol. The rate of symbols will affect the bandwidth and each symbol consists of a large number of bits. Digital modulation techniques themselves are nonlinear and linear. Linear Modulation has an amplitude that is channeled in the form of a linear line. Linear modulation is used in wireless LANs. While nonlinear is more used on most smartphones and also wireless data systems.


In this discussion of analog vs digital communication, we can conclude that most countries prefer to use digital communication technology. The technology that supports digital communication is also smaller, making it easier to carry anywhere. The application is easier because it is portable, such as on phones, SMS, social media, and others.
