Filters in this class are specified by two parameters the cutoff frequency and the filter order The frequency response of these filters is monotonic and the sharpness of the transition from the passband to the stop band is dictated by the filter ord Multidimensions. Yunfei. . duan. . Hui . Pan. Bilinear interpolation . The concept of linear interpolation between two points can be extended to bilinear interpolation within the grid cell.. http://en.wikipedia.org/wiki/Bilinear_interpolation. Onufriev. Over-all: Very good idea to use more than one source. Good motivation (use of graphics). Good use of simplified, loosely defined -- but intuitive -- terms (e.g. "undisturbed"). Very good use of illustrative graphics for introduction of new concepts. Obviously, took quit a bit of effort to prepare the talk. This very serious effort offsets some of the drawbacks, see below..

A Sampled or discrete time signal x[n] is just an ordered sequence of values corresponding to the index n that embodies the time history of the signal. A discrete signal is represented by a sequence of values x[n] ={1,2,. Objectives. To give a definition of Interpolation as it relates to GIS and mapping/surveying. To explain How Interpolation Works.
