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.
Which standard governs parallel communication?
IEEE 1284
What are the subjects in the electronics and communication?
signal and system,digital logic design , engineering maths,
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.
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 is a open standard that uses digital communication of data and is accepted and used worldwide?
The generic name of such a standard is a "protocol".
An open standard that uses digital communication of data, and is accepted and used worldwide?
GSM
Why digital communication is known as digital communication?
because it's digital communication.
Why is digital communication known as digital communication?
In digital communication message is to be transmitted in digital form. That is why it is called so .
What are digital communication books related to uptu syllabus according to 6 sem?
Some recommended digital communication books that align with the UP Technical University (UPTU) syllabus for the 6th semester include "Principles of Communication Systems" by Taub and Schilling, "Digital Communications" by Simon Haykin, and "Digital Communications: Fundamentals and Applications" by Bernard Sklar. These books cover topics such as modulation techniques, signal encoding, communication channels, and digital transmission systems, which are commonly included in the 6th-semester syllabus for digital communication courses.
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.
Which US multiplexing hierarchy standard allows communication carriers to interconnect their existing digital and fiber optic systems?
Synchronous optical network (SONET)
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 digital communication device interfaces refrigerators with the Internet?
