Third-order polynomial model
WebApr 14, 2024 · In numerical analysis, sparse grids are point configurations used in stochastic finite element approximation, numerical integration and interpolation. This paper is concerned with the construction of polynomial interpolator models in sparse grids. Our proposal stems from the fact that a sparse grid is an echelon design with a hierarchical … WebFeb 28, 2024 · The third order intercept could be determined by the polynomial in this model. This is why the model with a polynomial to take into account non-linear distortion products, together with a “Noise Effective Number of Bits” to take into account quantization noise, clock jitter, and other noise-like phenomena is better.
