Importance of Digital Electronics Techniques : Digital Logic

Digital electronics techniques is most important in this current world. Because without digital electronics it's not possible to speed up our work. You can take a look of previous analog devices those are very slow and takes lots of time to find out the result. 

Digital electronics or digital circuits are electronics that handle digital signals- discrete bands of analog levels, rather than by continuous ranges (as used in analogue electronics). All levels within a band of values represent the same numeric value. Because of this discretization, relatively small changes to the analog signal levels due to manufacturing tolerance, signal attenuation or parasitic noise do not leave the discrete envelope, and as a result are ignored by signal state sensing circuitry.

Digital techniques are useful because it is easier to get an electronic device to switch into one of a number of known states than to accurately reproduce a continuous range of values.

Digital electronic circuits are usually made from large assemblies of logic gates, simple electronic representations of Boolean logic functions.[ntl]

Digital electronics involves in logic of 0 and . Where where 0 means Off and 1 means On.  It involves the devices and circuits such as gates, flip-flops, latches etc. The basic idea of Digital electronics is mandatory for microprocessor & micro controller and also for computer architecture. So, any application which involves microprocessor or a computer have digital electronics in it. It can be security applications, error correcting & error detecting , power saving circuits etc.

When to talk about the example of digital electronics we can see below figure for digital signal system 

Digital Signal

Digital signal is efficient rather than analog signal. We can say digital signal is efficient accurate and reliable to transmit data from one place to another. 

To take example of digital device we can see the example of digital computer...
