Summary: quadrature in Brief
The term 'quadrature' [kwäˈdraCHər] refers to several processes related to squares and rectangles. It can mean constructing a square with the same area as a given figure, determining the phase or amplitude of a periodic quantity, or simply being square or rectangular. Examples include the quadrature of the circle, quadrature of amplitude, and quadrature of a building's foundation. Quadrature extends into phrases like 'quadrature formula' and 'quadrature oscillator,' which denote mathematical and electronic applications.
