About the Authors
  • If you are working in digital signal processing, control or numerical analysis, you will find this authoritative analysis of quantization noise (roundoff error) invaluable. Do you know where the theory of quantization noise comes from, and under what circumstances it is true? Get answers to these and other important practical questions from expert authors, including the founder of the field and formulator of the theory of quantization noise, Bernard Widrow. The authors describe and analyze uniform quantization, floating-point quantization, and their applications in detail. Key features include: • Analysis of floating point round off • Dither techniques and implementation issues analyzed • Offers heuristic explanations along with rigorous proofs, making it easy to understand 'why' before the mathematical proof is given.

    • Focus is on practical cases so theory is understood through examples and homework problems
    • Program package for Matlab available on line, for simulation and analysis of fixed point and floating-point roundoff, allowing the reader to experiment with the ideas described
    • Instructor-solutions, links to key papers and Matlab programs available through the book's author-maintained web page: http://www.mit.bme.hu/books/quantization/
