It depends on applications. At the middle - short distances analog communication can be much more efficient than digital. If you work in communications, you may find the explanation - why? in IEEE Comm. Letters, vol.16, no. 5, 2012, pp.573-576, as well as in my Research Gates Profile. With regards.

Why we use periodic analog and non periodic digital signal in communication?
In data communication computer use periodic analog signal because it Need Less Bandwidth. So, by using Periodic Analog Signals it is easy to select the Medium through Which data is travelled otherwise it is Much Difficult (aprox. Impossible ) .
Is speaker output analog or digital?
Bluetooth is a digital communication interface. It tends to be used for audio signals more than other applications so it is often perceived as carrying analog audio. Despite the appearance, it is definitely digital and not analog.
Is baseband digital or analog?
Both, Like any other form of communication. However, all analog forms of communication/transmission will end in February of 2009. All manufactures have already changed to the digital format, therefore in a couple of months any older system will be obsolete.
What are the advantages of using digital signals and why?
* 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.
What are analog and digital modes of operation of an instrument?
In Analog communication, the analog message signal modulates some high carrier frequency inside the transmitter to produce modulated signal.this modulated signal is then transmitted with the help of a transmitting antenna to travel through the transmission channel. At the receiver, this modulated signal is received and processed to recover the original message signal. Example: AM , FM radio transmission an TV transmission. In digital communication, the message signal to be transmitted is digital in nature. This means that digital communication involves the transmission information in digital form Example: ASK, FSK, PSK.
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.
Why you use analog communication?
Because I am an analog creature living in an analog world. If I were a computer I would use digital communication. :-/ ?
Difference between analog communication and digital communication?
Analog communication considers infinite amplitude levels. But in digital communication only 2 levels of signal is present.
Types of communication channel?
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.
What are the advantage of analog communication?
more easy to generate.easy way of communication
What are the types of telecommunications?
Analog communication & Digital
What is scrambling in data communication?
to secure analog data is called scrambling in data communication
What is analog data in data communication?
vivian is dumb
What are the advantages of analog?
Advantage of Analog Communication: 1)Transmission bandwidth required is less. 2)No need of synchronization.
Differentiae analog communication system with digital communication system?
digital coommunication is a mode of communication where the information is encoded digitally as discrete signals & electronically transferred to the recipients. analog communication format is that in which information is transmitted by modulating continuous signal, such as sound wave.
Exampl for analog communication?
In Analog communication, the analog message signal modulates some high carrier frequency inside the transmitter to produce modulated signal.this modulated signal is then transmitted with the help of a transmitting antenna to travel through the transmission channel. At the receiver, this modulated signal is received and processed to recover the original message signal. Example: AM , FM radio transmission an TV transmission.
What kind of modulation used for land phone communication system?
Analog
