Computational Considerations in Analysis
The implementation of linear prediction techniques for all but trivial examples requires digital computation. In nearly all of the material presented thus far, an implicit assumption was made that the computation occurred without error. For example, the norm squares α m and β m of Chapter 3 are theoretically non-negative, yet when they are evaluated using the computer programs presented they may yield negative results due to computer errors. Numerical results are a function of the algorithms used, the form of computer arithmetic (e.g., floating or fixed point), and the computer word length.
