The K3 and thus presumably the K3S implements one particular form of the Least Mean Squares algorithm called the Leaky LMS, see Lyle's response some years ago: http://elecraft.365791.n2.nabble.com/K3-NR-td1557606.html#a1557836
That's an adaptive version of a Wiener filter that doesn't get so easily 'stuck' in a non-optimal solution if signal statistics should change drastically. Instead the non-optimal solution 'leaks' out of the filter. The Wiener filter by itself is a fixed signal-to-noise optimizing filter, and thus is fundamentally different from low pass, high pass etc in that the filter's coefficients depend on the input signal. ----- Sverre, LA3ZA K2 #2198, K3 #3391, LA3ZA Blog: http://la3za.blogspot.com, LA3ZA Unofficial Guide to K2 modifications: http://la3za.blogspot.com/p/la3za-unofficial-guide-to-elecraft-k2.html -- View this message in context: http://elecraft.365791.n2.nabble.com/Does-the-K3S-DSP-support-LMS-noise-reduction-tp7605863p7606068.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
