Is digital electronics is the best or analog electronics?
They have their own merits and demerits you can't say digital electronics is best because in real world everything is available in analog quantity. Although Digital electronics is more reliable in comparison of analog because there is very high reliability in the sense (effect of noise) and correction of errors that occurred during transmission of digital signal, while this is not possible in analog communication.
How do you convert the analog fuel level indicator into digital in cars?
A: By adding an ADC analog digital converter but then again false triggering and monotonic and other errors makes this approach not desirable. unless heavily filtered the numbers will just rolls by filtering you get back again to analog response.
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 are Disadvantages of digital control?
Unwanted Errors of precision when the analog signal is converted into a quantized, sampled digital signal. The same error arises when the digital signal is then converted into an analog signal for the plant to use.
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.
How can you digitize analog signal?
There devices called A/D oranalog to digital. where by a ref is setup and is basically compared to their input as more-less value. bits of data or 1-0 are output out to represent the analog input as digital bits . For a designer there are errors to be considered . resolution basally how much an lsb is worth in voltage. quantization uncertainty ,linearity errors offset errors full scale errors for gain control, monotonicity and finally conversion timing. lsb IS LEAST SIGNIFICANT BIT NOT POUNDS.

What is digital signal and how its different then analog signals?
Digital signals have discrete encoded states that they switch between. They can only assume the defined encoded values. Errors can often be easily detected and sometimes corrected.Analog signals are continuous and change smoothly from one value to another, passing through all intermediate values. There is no way to identify errors.
How is analog computers are more powerful then digital computers?
Digital computer uses discretely coded numbers or symbols (typically in binary, although other codings like decimal and trinary have been used in certain machines). Changes in value are sudden jumps by at least the smallest representable value. Digital computers can incorporate error detecting and/or correcting circuits.Analog computer uses continuously varying signals. Changes in value are smooth and continuous. Analog computers drift with temperature, voltage, component aging, etc. and are very sensitive to noise; any of which can cause undetectable errors.
How the digital machines have changed the social life?
digital machines indeed a part of great transformation in social life. previously when digital machines were at the nascent stage people used the analog machines. this analog machines behaves with continuous input both in time as well as magnitude. so when an error is made out in the process, it justifies the error with large irritating noise with respest to analog signal. analog machines are prone to errors due to manhandling, sometimes for the erring machine itself. on the other hand, digital machines works on discrete time and also a discrete amplitude signal. boolean functions/laws of algebra are the fundamental blocks which build out the digital machines. the amplitudes are discreet and takes only two values 0 and 1. so there is a less probability of error while dealing with discreet functions that is less prone to noises, technical glitches etc. so digital machines plays a great role in social transformation!!
If all the computers are digital then why we say that most of the computers are digital?
All computers are not digital.Prior to the 1940s all computers that had ever been built were analog (only Charles Babbage's never built Analytical Engine designed in the 1830s was a digital computer in this period).Even after the 1940s many computers were still analog and other computers were hybrid (part digital, part analog to best use the advantages of each to solve the problems as quickly as possible, at the lowest cost possible, while getting the needed accuracy). The image above shows a hybrid computer from the 1960s, the plugboards on the middle two racks are the means of programming the analog part of this computer for different problems.In the 1980s I worked on an avionics box that the company I was employed by had designed for the Navy F/A-18A that contained 8 custom computers (6 digital and 2 hybrid) packed in a box 6 inches square by 2 feet long!The usage of analog (and thus hybrid) computers has declined dramatically since the introduction of the microprocessor (which dramatically reduced both the size and cost of computers) and especially since the introduction of a special purpose type of microprocessor called a digital signal processor(specifically designed to solve the types of problems analog computers had been traditionally used for, except entirely by digital means). However there do still remain a few problems for which an analog computer is the only reasonable solution: problems that require near instantaneous results but can tolerate imprecise results (analog computers have many error sources due to a combination of component tolerances, drift, noise, etc. that digital computers do not). Digital computers are also much easier to program or reprogram when programming errors are found than analog computers (many analog computers would actually have to be completely dismantled and reassembled or just thrown away and completely replaced to "reprogram" them).
What does a DVi-VGA cable do?
A DVI-D cable is a digital video display connector used in computers. It supports the same resolutions as VGA which has been the analog standard for many years. Digital signals do not suffer from timing errors that can sometimes reduce the clarity of an image delivered with VGA. Note that there are two other formats. DVI-A uses the DVI connector but it carries an analog signal identical to that of VGA connector. A DVI-I carries both digital and analog signals and therefore provides two video links within the same cable. Finally, DVI digital signals are compatible with HDMI video signals. DVI does not carry sound in either digital or analog video formats whereas HDMI supports sound within the same cable.
