Design elements - Analog and digital logic

The vector stencils library "Analog and digital logic" contains 40 element symbols of logic (threshold) gates, bistable current switches, current controllers, regulators, electrical generators, and amplifiers.
Use it for drawing the digital and analog functions in electronic circuit diagrams and electrical schematics.
"Analogue electronics (or analog in American English) are electronic systems with a continuously variable signal, in contrast to digital electronics where signals usually take only two different levels. The term "analogue" describes the proportional relationship between a signal and a voltage or current that represents the signal." [Analogue electronics. Wikipedia]
"Digital electronics, or digital (electronic) circuits, represent signals by discrete bands of analog levels, rather than by a continuous range. All levels within a band represent the same signal state. 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 a value near the supply voltage, corresponding to the "false" ("0") and "true" ("1") values of the Boolean domain respectively.
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." [Digital electronics. Wikipedia]

"Alpine skiing is the sport of sliding down snow-covered hills on skis with fixed-heel bindings. It is also commonly known as downhill skiing, although that also incorporates different styles. Alpine skiing can be contrasted with skiing using free-heel bindings; ski mountaineering and nordic skiing – such as cross-country; ski jumping; and Telemark. Alpine skiing is popular wherever the combination of snow, mountain slopes, and a sufficient tourist infrastructure can be built up, including parts of Europe, North America, Australia and New Zealand, the South American Andes, and East Asia.
Alpine skiing began as a club sport 1861 at Kiandra in Australia and a number of similar clubs in North America and the Austrian and Swiss Alps. Today, most alpine skiing occurs at a ski resort with ski lifts that transport skiers up the mountain. The snow is groomed, avalanches are controlled and trees are cut to create trails. Many resorts also include snow making equipment to provide skiing when the weather would otherwise not allow it. Alternatively, alpine skiers may pursue the sport in less controlled environments; this practice is variously referred to as ski touring, backcountry skiing, or extreme skiing.
In competitive alpine skiing races four disciplines exist: slalom, giant slalom, super giant slalom, and downhill. Slalom ski races have courses that require short tight turns, whereas giant-slalom races have courses which are set with more widely spaced turns. Super-giant slalom and downhill have few turns, the courses have gates spaced widely apart and skiers often reach 100 km/ h." [Alpine skiing. Wikipedia]
