Quadrature amplitude modulation ppt. In mathematics, quadrature is a historic term for the computation of areas and is thus used for computation of integrals. The integral is then computed by evaluating the antiderivative at the endpoints of the interval. There are some circumstances in numerical computations where it is easier to use a quadrature rule to evaluate the integral of a polynomial, rather than computing the integral directly from the polynomial coefficients. The word is derived from the Latin quadratus meaning "square". Oct 8, 2025 · Quadrature refers to determining the area of a plane geometric figure or computing an integral. Historically, it involved constructing a square with the same area as a given figure, hence its name from the Latin “quadratus” (square). Feb 14, 2026 · The word quadrature is also used to mean squaring: the construction of a square using only compass and straightedge which has the same area as a given geometric figure. It involves the process of determining the area under a curve, which is essential for solving many real-world problems. .
