Effects of finite register length in digital filtering and the fast Fourier transform
Alan V. Oppenheim,C. Weinstein +1 more
TL;DR: The groundwork is set through a discussion of the relationship between the binary representation of numbers and truncation or rounding, and a formulation of a statistical model for arithmetic roundoff, to illustrate techniques of working with particular models.
Journal ArticleDOI
Roundoff noise in floating point fast Fourier transform computation
TL;DR: A statistical model for roundoff errors is used to predict output noise-to-signal ratio when a fast Fourier transform is computed using floating point arithmetic, and it is found experimentally that if one truncates, rather than rounds, the results of floating point additions and multiplications, the output noise increases significantly.
Journal ArticleDOI
A comparison of roundoff noise in floating point and fixed point digital filter realizations
C. Weinstein,Alan V. Oppenheim +1 more
TL;DR: In this article, a statistical model for roundoff noise in floating point digital filters, proposed by Kaneko and Liu, is tested experimentally for first and second-order digital filters.
Journal ArticleDOI
Teminology in digital signal processing
Lawrence R. Rabiner,J.W. Cooley,H. Helms,Leland B. Jackson,J. Kaiser,C. Rader,R. W. Schafer,Kenneth Steiglitz,C. Weinstein +8 more
TL;DR: This paper proposes terminology for use in papers and texts on digital signal processing which it is felt is self-consistent, and which is in reasonably good agreement with current practices.
Journal ArticleDOI
Predictive coding in a homomorphic vocoder
C. Weinstein,Alan V. Oppenheim +1 more
TL;DR: Application of a type of predictive coding to the channel signals of a homomorphic vocoder has produced sizable bit rate reduction and a technique for obtaining the formant frequencies from the predictive coding parameters is described; this approach promises further bit rate reductions.
