This signal component can further be used to calculate a desired parameter of the sample. The DC component of the signal is determined as the median value of the upper envelope, and the AC component is determined as the median value of the difference between the upper and lower envelopes.

Why it's free to use
- Filed October 15, 2001 and granted January 10, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 15, 2021.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
