Digital electronics
Digital electronics or digital (electronic) 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.In most cases the number of these states is two, and they are represented by two voltage bands: one near a reference value (typically termed as ""ground"" or zero volts), and the other a value near the supply voltage. These correspond to the ""false"" (""0"") and ""true"" (""1"") values of the Boolean domain, respectively, yielding binary code.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.
