A quantizer that adaptively determines a value of an optimum threshold for quantizing an analog signal to minimize the overall quantizing error rate by observing signal strengths of said analog signal. It comprises a histogram generator that generates histograms that indicate said signal strengths of said analog signal an optimum, reconstruction level generator that uses said histograms to generate optimum reconstruction levels by determining minimum mean squared errors; and an optimum decision threshold generator that uses said optimum reconstruction levels to generated optimum decision thresholds by determining the average of said optimum reconstruction levels.

Why it's free to use
- Filed December 29, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 29, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 29, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
