What is sinc interpolation?
Sinc interpolation implies signal interpolation where a certain bandwidth is assumed. The interpolation accuracy depends on the data to be interpolated. If the data is a signal that is truly band limited to let’s say F b with a sampling rate F s, then s i n c ( 2 ? F b t) is an exact interpolation.
What is the interpolation procedure?
The interpolation procedure has three major steps: (1) building and calibrating a nonlinear TFN model using groundwater level data, (2) quantifying the temporal correlation in the residuals, and (3) interpolating the residuals to the interpolation time points and adding them to the TFN simulated water level.
What is Gaussian interpolation?
The technique of producing additional data points from a given collection of data is known as interpolation. Gaussian interpolation is classified as part of the Central Difference Interpolation Formulae, which varies from the Forward Interpolation Formula of Newton.
What is the purpose of Chapter 3 of interpolation?
Chapter 3. Interpolation. Interpolation is the process of de?ning a function that takes on speci?ed values at speci?ed points. This chapter concentrates on two closely related interpolants: the piecewise cubic spline and the shape-preserving piecewise cubic named “pchip.”.
