What are the Advantages of analog and digital communications?
Disadvantage of Analog Communication: 1)Analog Communication systems are costlier than digital communication system. 2)Less Security in Analog Communication 3)More prone to noise interference. Advantage of Analog Communication: 1)Transmission bandwidth required is less. 2)No need of synchronization. Advantage of Digital Communication: 1)Digital Communication systems are simpler and cheaper. 2)Using data encryption only permitted user are allowed to detect the transmitted data. 3)Since in Digital Communication, channel coding is used, therefore a large amount of errors may be detected 4)Since transmitted signal is digital in nature,large amount of noise tolerance may be tolerated Disadvantage of Digital Communication: 1)More transmission bandwidth required. 2)Digital Communication needs synchronization in case of synchronous modulation.
What is fixed equalizer in digital communication?
fixed/statistical equilazer
What are the advantages of digital communications over analog communication?
Using analogue communication from a digital interface requires some kind of converter to convert your digital data into analogue before it can be sent. This data needs to be converted back into digital by the receiver. Hence a larger amount of work needs to be done. eg: the VGA cable used to connect a PC to a screen is a analogue cable. So all the video signals that are sent out by your PC are converted to analogue first. Hence there is a larger amount of work done. There is also a chance of data being lost during this conversion. If the source signal and the output signal are digital, then there is no conversion required and resulting work required is less. This also means that the receiver doesn't need to convert this data. Hence work done is less and data loss in conversion is also minimal. Although transmitting digital data over long distances also results in some amount of loss. eg: video signals transmitted through DVI or HDMI cables are purely digital. A PC or Blu-Ray player connected to a digital screen using any of the above interfaces doesn't need to convert the signal before sending it. Hence data loss is minimal and resulting picture is sharper and accurate.
What are the disadvantages of analog communication?
Disadvantage of Analog Communication: 1)Analog Communication systems are costlier than digital communication system. 2)Less Security in Analog Communication 3)More prone to noise interference.
What is the scope of digital communication?
Digital communications has a lot of scope in our life . For example, all the cellular networks,internet and other advanced communication systems are based on digital technology. So, there are a lot of companies growing in this sector.Today, fast and cheap communication has become the demand of public and thus there is a huge competition between companies to sustain in the market.
Why digital communication is known as digital communication?
because it's digital communication.
Define line coding in data communication?
process oftransfer of digital data to digital signal is known as line coding
How data communication and digital communication differ?
In digital communication we talk about signal while in data communication we talk about data and the could be in the form of packets or frames.
Difference between analog communication and digital communication?
Analog communication considers infinite amplitude levels. But in digital communication only 2 levels of signal is present.

What digital communication device interfaces refrigerators with the Internet?
A digital message board.
Definetion of nyquist rate in digital communication?
if the sampling rate is twice that of maximum frequency component in the message signal it is known as nyquist rate
What is the today's era?
We are currently in the digital age, also known as the Information Age or the Fourth Industrial Revolution. This era is characterized by the widespread use of technology, the internet, and digital communication in various aspects of our lives.
What are the types of telecommunications?

What has the author Yoshihiko Akaiwa written?
Yoshihiko Akaiwa has written: 'Introduction to digital mobile communication' -- subject(s): Digital communications, Mobile communication systems
What are the capabilities of digital communication systems?
A digital communication system consists of six basic blocks. The functional blocks at the transmitter are responsible for processing the input message, encoding, modulating, and transmitting over the communication channel.
