Linear Methods of Approximation
1990An operator L, defined on BΩ ⊂ AΩ, is called linear if L(αf + βg;x) = αL(f; x) + βL(g; x), for all f, g ∈ BΩ and for all constants α, β, and it is called positive if L(f; x) ≥ 0 for all x ∈ Ω whenever f(x) ≥ 0 for all x ∈ Ω.

METHODS OF APPROXIMATING SENSOR NON-LINEARITY
THE ROLE OF STANDARDIZATION IN MANUFACTURING, 2022This article examines the nonlinearity of sensors, which is one of the most important descriptions, and the methods of its linearization by approximation. It is important that the sensor transmission function is linear, and based on this description, the sensor is graduirovated.

Linear Controller Approximation: A Method with Bounds
IFAC Proceedings Volumes, 1985Abstract The problem of approximating a high order controller by a low order one is tackled with the aid of a frequency-weighted Hankel norm approximation procedure. Bounds are obtained which weight those arising in the unweighted Hankel norm approximation procedure by a factor depending solely on the weighting function.

A new Toeplitz approximation method for linear prediction matrices
IEEE International Conference on Acoustics Speech and Signal Processing, 1993A method for constructing the reduced-rank Toeplitz approximation matrices to the linear prediction matrices of the covariance matrices is proposed. This method uses the power method to reduce the computation time compared with the conventional method. As a practical application, the harmonic retrieval problem is considered in the case of an input data
