The symbol generator can go by other names, such as display processing computer, display electronics unit, etc. The symbol generator does more than generate symbols. It has (at the least) monitoring facilities, a graphics generator and a display driver. [2] Inputs from sensors and controls arrive via data buses, and are checked for validity.
Given an independent variable x and a dependent variable y, y is directly proportional to x [1] if there is a positive constant k such that: = The relation is often denoted using the symbols "∝" (not to be confused with the Greek letter alpha) or "~", with exception of Japanese texts, where "~" is reserved for intervals:
A DC armature of a miniature motor (or generator) A partially-constructed DC armature, showing the (incomplete) windings In electrical engineering, the armature is the winding (or set of windings) of an electric machine which carries alternating current. [1]
Three-phase transformer with four-wire output for 208Y/120 volt service: one wire for neutral, others for A, B and C phases. Three-phase electric power (abbreviated 3ϕ [1]) is a common type of alternating current (AC) used in electricity generation, transmission, and distribution. [2]
The official chart of the IPA, revised in 2020. The International Phonetic Alphabet (IPA) is an alphabetic system of phonetic notation based primarily on the Latin script.It was devised by the International Phonetic Association in the late 19th century as a standard written representation for the sounds of speech.

In an electrical generator, a time-varying magnetic field inside the generator creates an electric field via electromagnetic induction, which creates a potential difference between the generator terminals. Charge separation takes place within the generator because electrons flow away from one terminal toward the other, until, in the open ...
The names of the taijitu are highly subjective and some interpretations of the texts they appear in would only call the principle of taiji those names rather than the symbol. [further explanation needed] Since the 1960s, the He tu symbol, which combines the two interlocking spirals with two dots, has more commonly been used as a yin-yang symbol.
