Open the CIPO recordAbstract From the Canadian patent
An oversampled, noise shaping signal processor (300) is described having at least one integrator stage (306) in the loop. A sampling stage (310) is connected coupled to the at least one integrator stage. The sampling stage samples an analog signal at a sample frequency. Qualification logic (318) coupled to the sampling stage receives a pulse waveform therefrom and ensures , that signal transitions in the pulse waveform occur more than a first time period apart and that the waveform can therefore be handled by for example, a , power switching device (312). A switching stage (312) in the loop is coupled to the qualification logic. The signal processor (300) has a feedback path from the …

Why it's free to use
- Filed July 20, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 20, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 20, 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.
