What is the main advantage of digital transmission over analog transmission?
digital signal is less susceptible to signal degradation due to the nature of it's transmission signal which is either on or off and therefore less errors occur as analog is prone to signal degradation and loss that is why digital tv is crisp and clear and analog is somewhat blurry in comparison, also with higher bandwidth achievable by digital transmission more data is able to be transmitted.
What type of signal degrades the most over longer distances?
digital
Are digital transmissions modulated over a carrier?
yes for transmission of the signal to take place smoothly,digital tranmission needs to be modulated over a carrier
What advantage do regenerative repeaters have when used for digital communication?
When any digital signal is transmitted over a pair of wires, it degrades in amplitude. Regenerative repeaters receives the incoming signal, extracts the clock, then regenerates the original signal as a clean digital square wave as if it was the original signal transmitted from the source. Thus the name repeater.
Does a digital signal travel farther than an analog signal?
You need to make a distinction between analog and digital signals, and analog and digital data. Digital data can be sent on an analog signal by using a modem. Digital data sent on a digital signal is done over a wire using voltage pulses at two or more levels. Digital signals can't travel very far without amplifiers, but analog signals can cover huge distances, such as with satellite communications and even communications with deep space probes.
What are the Advantage of digital modulation over analog modulation?
1)digital modulation can easily detect and correct the noise. where as analog modulation has little complexity 2)security is more in digital modulation 3)digital modulated signal can traverse a long distance compared to analog modulation

How to change digital signals to analog signals and again from analog to digital signals?
modem Measuring usually the voltage of the analog signal many times a second in binary number code generates a digital signal, and using a binary number code to control the voltage of an output results in a reproduced analog signal. That is what is done for stuff like digital television. A Modem (prior answer) is for when the analog signals are used to connect digital computers (like yours) together, usually over a long distance.
Why do you use modem?
modem means modulator demodulator. it converts digital signal to analog signal. it is use to transmit computer signal (digital signal) over the telephone line to communicate to other computers. modem converts the computer digital signal into frequency (analog signal) so that it can transmit over the telephone line and at the receiving end the modem converts the analog signal back to digital for the receiving computer to understand it.
What is advantage of digital signal processing?
Digital is always preferred over analog for the following reasonsAccuracyImmune to noiseEasy error detection and correctionThe same is true for digital signal processing too.

Which cell sends signals over long distance?
That depending on the type of the cable................. If you transmitt over a long distance eventhoogh we can use fiber but it may cost cost effective.......
What is loss of signal over distance called?
Attenuation
Are digital transmissions modulated over a carrier?
yes for transmission of the signal to take place smoothly,digital tranmission needs to be modulated over a carrier
Why FM signal is more local and cannot be transmitted over long distance?
Since FM signals have shorter wavelength and high frequency, it is diffracted much. Therefore it is not suitable for long distance communiation.
What is the difference between podcasting and older medium of radio?
Analog radio was broadcast from a studio out to listeners for a certain distance. Digital Radio is similar in what is broadcast but the quality of signal is better with Digital then analog. Podcasting is done over the Internet and is a rebroadcast of radio
