17 Interpolation Solutions to Recommended Problems S17.1 It is more convenient to solve this problem in the time domain than in the frequency domain. Since x,(t) = x(t)p(t) and p(t) is an impulse train, x,(t) is a sampled ver­ sion of x(t), as shown in Figure S17.1-1. x,(t) xP\ t -4T 0 4T Figure S17.1-1 x(t) = x(t) bt - nT) n= -oo

Linear Interpolation • Linear interpolation is obtained by passing a straight line between 2 data points = the exact function for which values are kn own only at a discrete set of data points = the interpolated approximation to the data points (also referred to as interpolation points or nodes) • In tabular form: y f(x 1) f(x 0) x 0 x 1 f(x ...

Newton Interpolation We have seen two extreme cases of representations of polynomial interpolants: 1.The Lagrange form, which allows you to write out P n(x) directly but is very complicated. 2.The power form, which is easy to use but requires the solution of a typically ill-conditioned Vandermonde linear system.

A Basic Interpolation Problem HARRY DYM Abstract. A basic interpolation problem, which includes bitangential ma-trix versions of a number of classical interpolation problems, is formulated and solved. Particular attention is placed on the development of the prob-lem in a natural way and upon the fundamental role played by a special

Lagrange Interpolation Calculus provides many tools that can be used to understand the behavior of functions, but in most cases it is necessary for these functions to be continuous or di erentiable. This presents a problem in most \real" applications, in which functions are used to model relationships between quantities,

An alternative approach to the interpolation problem is to consider directly a polynomial of the form Q n(x) = Xn k=0 b kx k, (3.8) and require that the following interpolation conditions are satisfied Q n(x j) = f(x j), 0 6 j 6 n.
