1.having low noise as compare to analog. 2.using TDMA Iinstead of FDMA techniques used in analog. 3.in digital signals regenrative repeaters are used at every regeneration point of the signals so low loss of signals are there as compare to analog signals

∙ 11y ago- digital systems have definite defined states, analog systems have continuous states with no definite value.
- if you need more defined states they can be added in a digital system simply by adding more bits to the value, in an analog system more uniquely defined values can only be added by using expensive precision tolerance components.
more states/values = more accuracy

What is the clock time of analog to digital converters?
The clock time of analog to digital converters depends on the design of the converter, which depends on the performance expectations for the system.
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.
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 is the difference between analog and digital data transmission?
This is essentially the same question as the difference between analog and digital. With analog electronics a voltage is used to represent (or to be an analogy for) some physical attribute in the real world. So for an analog transmission, at its simplest, a sound signal (say) is converted to a voltage, the voltage sent down a cable, then at the other end the voltage converted back into sound with a loudspeaker. With a digital system, the physicial attribute is measured and sent as a series of numbers, the numbers being converted to binary. For a digital transmission, the sound signal is converted to a series of numbers, sent as binary, and converted back to a sound signal at the other end. The advantages of digital is that it makes multiplexing much easier - making it easier to put many signals down the same physical cable. It also makes compressing the signal much easier - this is particularly effective for digital television transmission; 30-40 digital channels can be sent over the same bandwidth as 4 or 5 uncompressed analog channels. Also, digital is much more resiliant against noise - the digital receiver has to make a decision about each bit - is it there or not; noise can be pretty extreme before this becomes impossible, with analog, once noise is added its very difficult to remove it. The historical disadvantage of digital is that digital encoding and decoding equipment was expensive compared with the analog. Over the last 10 years or so, digital electronics has become much cheaper and more powerful.
What is Automobile Gas Pedal an analog system or an digital system?
In carbureted cars, this is completely an analog function, from pedal to carburetor throttle body. On electronic fuel injected cars, this is part analog and part digital. The part where your foot controls the position of the accelerator is analog, then this position information is digitized and sent to the cars control computer where the position information is translated into an engine RPM request. This digital request is sent to a sophisticated fuel/air control algorithm which increases/decreases the injector activation control period in relation to the volume of in rushing air measurement. The digital side of an injection control scheme is a pretty delicate balance of engine part design knowledge, such as cam lift/open duration/close timing. This is why if you change a physical feature of an engine that is computer injection controlled, the computer needs to be reprogrammed in order to take advantage of the change.
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.
Difference between an analog pbx and digital pbx?
Analog PBX is telephone system that is capable of handling calls and phone logs. Digital PBX is a system bundle with phone capabilities, fax, and other internet features. Digital PBXs are usually interfaced with computers and are internet-based.
What is digital analog simulators?
Analog system simulation is more sensitive to the changes in the parameters compared to the digital system. This is because of the continuous nature of the analog signals, unlike the discreet nature of the digital signals. Digital systems have gates which can not be used in Analog system.

What are the differences between analog system and digital system?
Analog would be like a sliderule which is based on logarithms. Digital would be like a calculator.
What is a analog-to-digital converter chip?
Its an IC which converts the analog signal at its input into digital output suitable for digital applications. It is an essential part of any digital system

What are the advantages of analog system and digital system?
An analog system is usually simple requiring few components and gives results almost instantlyA digital system gives repeatable results with no drift or temperature sensitivity that can be as precise as desired
Difference between analog audio and digital audio?
In analog ckt there is more distortion but in digital there is no distortion. Analog is a continues value digital is a discrite value(0 or 1). To measure analog is very difficult but in digital it is very easy. compare to analog the digital system is very compart for us. H.L.Kiran
How do analog sound systems compare to digital systems?
