What Are The Limitation Of Digital Communication?

What are the disadvantages of digital communication Mcq?

What are the disadvantages of digital communication.

Explanation: Digital communication needs more bandwidth, has higher complexity and little performance degradation occurs during analog to digital conversion and vice versa..

Why do we need digital modulation?

Digital modulation is used to transfer a digital bit stream over an analog channel at a high frequency. This enables us to transmit signals generated in a digital circuit across a physical medium. This is because digital signals can be handled with higher security and digital systems are readily and widely available.

Is Analog better than digital?

Digital recordings can have a greater signal-to-noise ratio depending on the bit depth of the recording. … This jump in elevation can create a digital noise. The smooth analog signal matches the recorded sound wave better than the steps of a digital recording.

Why is digital data not easily affected by noise?

Why is digital data not easily affected by noise? Explanation: Noise is inevitable in a signal transmission. In a digital transmission the amplitude of the noise must be higher than the amplitude of the signal at binary ‘1’, which is generally not the case, and vice versa.

Which has lower noise immunity?

Explanation: TDM is used to use only one carrier frequency to handle different signals. … Explanation: TDM has lower noise immunity.

What is the importance of digital age?

The early 90s saw the rise of the information age. Network connected computers and digital communication meant businesses were able to collect and leverage customer data to help develop new business models.

What are the limitation of digital modulation?

Due to analog to digital conversion, the data rate becomes high. therefore more transmission bandwidth is required for digital communication. Digital communication needs synchronization in case of synchronous modulation.

What are the advantages of digital modulation?

An advantage of digital modulation is that it can operate with much lower signal-to-noise ratio than can analog modulation, as shown in Figure 4.13. Also, output level is not dependent on optical level, and there is no degradation of signals through the system (to the point that they go away, of course).
