A signal notching system reduces signal peaks by notching the peak of a signal above a threshold to produce a notched signal. The notched signal is then filtered to, produce a resulting signal with a reduced peak amplitude. For example in an, implementation where the signal is represented by signal samples the peak , notching, system first locates a peak sample that is beyond a threshold such as a , sample, representing a positive peak sample of a peak above the threshold. Once a peak sample is, located, the peak notching system adjusts the peak sample by an amount which is a, function of the amount that the peak sample is beyond the threshold effectively creating, a notched signal with …

Why it's free to use
- Filed July 20, 2000 and granted December 2, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 20, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 20, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
