The Digital Electronics Basics Series presents the fundamental theories and concepts taught in entry-level electronics courses in both 2-year and 4-year institutions. This series of content provides examples to teachers so they can easily teach concepts to students, who can develop a solid underlying knowledge of digital electronics using the NI solution. Digital electronics or digital (electronic) circuits are electronic that handle digital signals (discrete bands of Analogs) instead of continuous intervals like those used in analog electronics. All levels within a range of values represent the same information state. Due to this discretization, relatively small changes in the analog signal levels due to fabrication tolerance, signal attenuation or noise do not leave the envelope discrete, and as a result are ignored by signal state detection circuits.
In most cases, the number of these states is two, and are represented by two voltage bands: one near a reference value (usually called "earth" or zero volts) and the other a value close to the Supply voltage. These correspond to the false and true values of the Boolean domain, respectively. Digital techniques are useful because it is easier to get an electronic device to switch to one of several known states than to accurately reproduce a continuous range of values. Digital electronic circuits are generally made up of large sets of logic gates, simple electronic representations of Boolean logic functions.
