Why digital is cheaer than analog?
Digital is cheaper for two possible reasons. The answer will be determined by your question of type of digital as in physical components or radio based transmissions. Number one: Digital devices can be made smaller with less components than analog. Number two: More information can be transmitted over the same available transmission space using digital than can be with analog.
Different types of signal encoding technique?
n Digital data, digital signal n Equipment less complex and expensive than digital-to-analog modulation equipment n Analog data, digital signal n Permits use of modern digital transmission and switching equipment n Digital data, analog signal n Some transmission media will only propagate analog signals n E.g., optical fiber and unguided media n Analog data, analog signal n Analog data in electrical form can be transmitted easily and cheaply
Are digital phones as reliable as analog phones?
Digital phones are more reliable than analog phones. The digital signals are easier to produce and the technology is more reliable than that of analog signal.
Why are digital systems capable of greater accuracy than analog system?
Greater possible accuracyNo driftNo temperature sensitivityReduced noiseNo aging problemsEasier to change if neededHowever where speed of response is critical the analog control system may be preferred over digital.
Why digital and analog ground must be separated?
Digital GND has more noise than Analog GND. So never mix up Digital GND to Analog GND to avoid the coupling from Digital to Analog GND
Why did you have to change to digital TV?
The move to digital television broadcasting reflects the change in production, storage and viewing of television content. Digital transmission adds features that analog services are unable to support and there is a flexibility in the use of transmission bandwidth that is also not possible with analog broadcasts. As far as the viewer is concerned, digital television broadcasts allow far more channels to be received and normally with better image quality than seen with analog.
Why scanning is necessary in tv transmission?
scanning is done to sample the image as digital information is more easy to be transmitted than the analog information...
What are the disadvantages of having an analog watch?
The advantages of an analog watch over a digital watch are that analog watches can be more durable in some facets, than a digital one. Many watch enthusiasts also feel that analog watches are more aesthetically pleasing than digital watches.
Why is there less interference with digital signals than analog signals?
Analog signals require higher fidelity than digital signals because digital are either on or off while analog are continuous. A small difference in an analog signal is not detectable while it requires a large difference to turn on into off (digital signal). Error correction is easier with digital signals.
Why is it necessary to digitize voice signals?
To minimize the distortion of analog signals during transmission Because digital lines transmit signals more efficiently across distances than analog lines Because many telephone networks are moving over to digital interfaces
How are digital aerials different from analog ones?
Digital aerials get a better quality of picture than do analog aerials. in addition, digital aerials can get high definition signals over the air,where analog aerials cannot.
What are the advantages of a digital radio over an analog radio?
The advantages of digital radio over analog radio are digital radios get more channels than analog, they are clearer in sound and signal and have more additional features.
