What is digital communication in simple words?
Simply said, digital communication involves an organization’s online communication efforts. Most organizations today use a wide range of online channels—from their website to mobile chat to blogs—to connect with current and prospective customers, employees, and other stakeholders.
What are the two types of digital communication?
Types of Digital Communication
- The Internet and Email.
- Cell Phones.
- High-Definition Television.
- Other Electronic Communication.
- Physical Digital Media.
How does digital communication system work?
In a Digital Communication System, the messages generated by the source which are generally in analog form are converted to digital format and then transmitted. At the receiver end, the received digital data is converted back to analog form, which is an approximation of the original message [1].
What is digital communication systems?
Digital communication systems, by definition, are communication systems that use such a digital1 sequence as an interface between the source and the channel input (and similarly between the channel output and final destination) (see Figure 1.1).
What are the 3 elements of digital communication?
Elements of Digital Communication
- Source. The source can be an analog signal.
- Input Transducer. This is a transducer which takes a physical input and converts it to an electrical signal (Example: microphone).
- Source Encoder.
- Channel Encoder.
- Digital Modulator.
- Channel.
- Digital Demodulator.
- Channel Decoder.
What are the basic elements of a digital communication system?
Basic Components of a Digital Communication System
- Source.

What is necessary for digital communication?
3. What is necessary for digital communication? Explanation: Bit, character, frame synchronization and precision timing is necessary for digital communication. This is considered as a disadvantage of digital communication.
What are the advantages of digital communication system?
Advantages of Digital Communication Digital circuits are more reliable. Digital circuits are easy to design and cheaper than analog circuits. The hardware implementation in digital circuits, is more flexible than analog. The occurrence of cross-talk is very rare in digital communication.
