Advantage of Analog Communication: 1)Transmission bandwidth required is less. 2)No need of synchronization.
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.
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.
Because I am an analog creature living in an analog world. If I were a computer I would use digital communication. :-/ ?
1-What are the advantages of sampling analog signals?2-what are the following terms mean : instantaneous Sampling , Natural Sampling , and Flat-top Sampling ?3- what are the advantages of digital communication over analog communication ?4-Explain the reason for making the sampling frequency greater than or equal to (2B)Hz , where B is the bandwidth of the analog signal
Analog communication considers infinite amplitude levels. But in digital communication only 2 levels of signal is present.
The two types of communication channel are analog and digital communication channel. An analog channel uses continuously varying (analog) electrical signals while a digital one uses discrete signals.
* Digital signals suffer less interferences than analogue signals. This means that when you listen to a digital signal you won't hear a hissing sound, as within digital signals regenerator circuits are used to clean "noisy" pulses. * Digital signals can be made very short so more pulses can be carried around each second, which means more information can be passed on.
