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 digital and analog?
we often confuse our-self with continuous time and analog signals. An analog signal is a signal which can take any amplitude in continuous range that is signal amplitude can take infinite values on the other hand a digital signal is one whose amplitude can take only finite numbers of values THE TERM CONTINUOUS SIGNAL AND DISCRETE SIGNAL CLASSIFY THE SIGNALS ALONG THE TIME (i.e. horizontal axis) where as THE TERM ANALOG AND DIGITAL SIGNAL CLASSIFY THE SIGNAL ALONG THE AMPLITUDE (i.e vertical axis)
Why are digital system capable of accuracy than analog system?
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
What is the difference between an analog ic and a digital ic?
digitals ICs output either a high, +5v DC, or a low 0v. The outputs of digital ICs or on-off-on-on-off....etc. Analog ICs output waves in forms of sine, tri, basically anything but Square waves. Analog ICs usually used to regulate, amplify, filter, existing waves comming into its inputs. The digital ICs output a on-off signal based on what signals you give it. Analog ICs are not absolute, they are used in almost every design. Don't know where these other people got there info from, like they are based on PCB boards, wrong, they are based on silicon wafers they look exactly like digital ICs. Sure these Analog ICs may include some digital circuityry but their output is always analog and they are used in almost EVERY electronic/electrical device
What do you mean by analog signal and digital signal?
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.
Signal has 0-1 values. is this will be analog or digital signal?
If the values are only 0 and 1 then the signal is digital.
Whats the difference between analog and digital signal?
Analog signals are continuous while digital signals are discrete
What are types of data that can be electronically transferred?
In theory any data can be transferred electronically in the form of a organized series of values of zero(s) and one(s). Any kind of data is converted into digital form from analog form using ADC i.e. Analog to Digital Converter and then it is able to transfer over an electrical medium.
Differentiate between an analog and a digital electromagnetic signal?
1. Digital Signal is non-continuous signal where as analog is continuous signal 2. Digital signal contain only two value that is 0 or 1,or high or low where as analog contain all the values in it's time interval 3.Chance of attenuation in analog is more then digital signal

What does digital data mean?
A digital signal is a physical signal that is a representation of a sequence of discrete values (a quantified discrete-time signal), for example of an arbitrary bit stream, or of a digitized (sampled and analog-to-digital converted) analog signal. The term digital signal can refer to either of the following:any continuous-time waveform signal used in digital communication, representing a bit stream or other sequence of discrete valuesa pulse train signal that switches between a discrete number of voltage levels or levels of light intensity, also known as a line coded signal or baseband transmission, for example a signal found in digital electronics or in serial communications, or a pulse code modulation (PCM) representation of a digitized analog signal.A signal that is generated by means of a digital modulation method (digital passband transmission), to be transferred between modems, is in the first case considered as a digital signal, and in the second case as converted to an analog signal.
What is an analog signal?
An analog signal is a continuous signal that contains time-varying quantities. Unlike a digital signal, which has a discrete value at each sampling point, an analog signal has constant fluctuations. netonplus.com
What is the different of analog mul-titester to digital mul-titester?
The difference between the analog mul-titester and a digital mul-titester is that an analoq mul-titester varies in continues scale while the digital mul-titester has discrete values that is zero (0) and one (1).
What is the meaning of data acquisition systems?
A data acquisition system covers any system that converts analog waves into digital values for processing. A sensor that detects temperature, for example, takes the analog information and converts it into digital information that can be processed.
What is analog thermometer?
It is analogue as it can have more than one value unlike digital which has two main values which are 1 or 0.
