where [Q.sup.1.sub.n](f) is the quadrature
applied on the interval [a,b].
Pradhan (1996) have constructed a quadrature
rule for approximate evaluation of (1) from two quadrature
rules of different type but of equal precision.
It helps in studying the real and the imaginary (in-phase and quadrature
) components of the complex signal.

In Chapter 5 of the book  published in 1983, Draux introduced a generalization of the Gauss quadrature
formula for approximating the real-valued linear functionals.The associated results in [45, 49], obtained independently of those from , can be considered as straightforward generalizations to the complex case.
Next, a model of the quadrature
booster is formulated.
For example, for p = 3 and the QNU quadrature
scheme, the IGA results are far superior to the Abaqus and Nastran shell elements even in the context of this simple linear elastic problem.
oscillators find diverse application in measurement systems [30-33] and in communication circuits, quadrature
mixers, SSB-modulator, vector generator, and data conversion.
One of the most important features of the SEM is that the computation of the Lagrange polynomials that are used for the approximation of solution is based on the same GLL-nodes that are necessary to calculate integrals over the region [[OMEGA].sup.e] using the Gauss-Lobatto-Legendre quadrature
The angular variable is usually discretized by replacing angular integrals with quadrature
To solve this problem, Shovan and Swati  proposed cubature quadrature
Kalman filter (CQKF): the algorithm adopts the same method for solving the spherical integral as CKF, but, for radial integral, arbitrary order Gaussian-Laguerre quadrature
formula is used to achieve a higher radial integral accuracy, so as to improve the filtering accuracy further.
Inside the motor housing, the linear optical quadrature
encoder is directly connected to the shaft for the greatest possible accuracy.
In addition, compared to Binary Phase Shift Keying (BPSK) signals, little work have been done on the bandwidth efficient Quadrature
Phase Shift Keying (QPSK) modulation signals in multicell DAS .
In this method, first the receiving AM radio signal containing HV noise is quadrature
sinusoid oscillators are widely used in orthogonal signal mixers, in PLLs and SSB modulators; some such oscillators based on various active devices, for example, voltage operational amplifier-VOA , CFOA [10,11], CDBA [12,13], CDTA , DDCC , CCCCTA , OTA , and DVCCTA [18,19], are reported.
