A: Analogue signal Direct voltage that varies in the low spectrum of frequency on digital signal the information is deciphered in micro seconds therefore the frequency must be hi the higher the better.

Is data is transmitted in the form of digital or analog?
both but for analog usually a frequency Carrier is required
What are the advantages of digital data compared to analog data?
Digital data requires less bandwidth than analog data (e.g. new digital television broadcast compared to old analog broadcast), so more data can fit in the same frequency (e.g. DSL compared to analog modems). This is the primary advantage, although it is also generally stated that data is easier to recover and more tolerant towards interference.
What is it called when you convert a digital signal to analog?
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
A device to place digital signals on an analog system and vice-versa?
DAC - Digital to Analog ConverterADC - Analog to Digital Converter
What are the differences between analog and digital filters?
The ANALOG FILTER used in analog circuits.The DIGITAL FILTER USED IN DIGITAL circuits.
What are the advantages of analog?
Advantage of Analog Communication: 1)Transmission bandwidth required is less. 2)No need of synchronization.
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.

Whose bandwidth is high digital or analog?
it could be either one, depending on application. need more information to answer.
What converts a message from digital to analog and analog to digital?
An DAC convert digital signal to analog signal i.e Digital to Analog Converter. An ADC convert analog signal to digital signal i.e Analog to Digital Converter.
Why do you have to get digital television?
Older TV sets use analog signals. In February, all TV signals that are now analog will become digital because it gives more efficient use of the bandwidth. Analog sets will not receive and interpret the images from a digital transmission. It's the same reason you can't use your old TV as a computer monitor.

How information is transmitted?
by analog to digital,digital to analog signal
What is the output of IR Sensors is it analog or digital?
Digital
How analog instrument interfaced with a digital instrument?
Analog instrument are interface with digital instrument with the help of analog to digital converter(ADC).ADC converts analog signals to digital signals.
What is it called when you convert a digital signal to analog?
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
Why digital signals are better than analog signals?
according to my view, to deal with digital signal is more easy then that of analog. and it also stable so many of the semiconductor circuits run only on dc signals...... i think doubt is clear now....
