Parametric equalization — Parametric equalizer (or parametric EQ ) is an electronic multi band variable equalizer device used in sound recording and live sound reproduction with Public Address systems ( PA systems ). Parametric equalization devices allow audio engineers… … Wikipedia
Parametric array — The parametric array is a nonlinear transduction mechanism that generates narrow, nearly sidelobe free beams of low frequency sound, through the mixing and interaction of high frequency sound waves, effectively overcoming the diffraction limit (a … Wikipedia
Minimal negation operator — In logic and mathematics, the minimal negation operator u! is a multigrade operator ( u {k}) {k in mathbb{N where each u {k}! is a k ary boolean function defined in such a way that u {k}(x 1, ldots , x k) = 1 if and only if exactly one of the… … Wikipedia
Multigrade operator — In logic and mathematics, a multigrade operator Ω is a parametric operator with parameter k in the set N of non negative integers. The application of a multigrade operator Ω to a finite sequence of operands (x1, …, xk) is typically… … Wikipedia

Propositional calculus — In mathematical logic, a propositional calculus or logic (also called sentential calculus or sentential logic) is a formal system in which formulas of a formal language may be interpreted as representing propositions. A system of inference rules… … Wikipedia
Operation (mathematics) — The general operation as explained on this page should not be confused with the more specific operators on vector spaces. For a notion in elementary mathematics, see arithmetic operation. In its simplest meaning in mathematics and logic, an… … Wikipedia
Exclusive or — The logical operation exclusive disjunction, also called exclusive or (symbolized XOR or EOR), is a type of logical disjunction on two operands that results in a value of “true” if and only if exactly one of the operands has a value of “true”. [… … Wikipedia
Boolean algebras canonically defined — Boolean algebras have been formally defined variously as a kind of lattice and as a kind of ring. This article presents them more neutrally but equally formally as simply the models of the equational theory of two values, and observes the… … Wikipedia
Truth table — A truth table is a mathematical table used in logic specifically in connection with Boolean algebra, boolean functions, and propositional calculus to compute the functional values of logical expressions on each of their functional arguments, that … Wikipedia
