Where Is the Laser Sinking the Heat? 5 13 (2/2/2013 4:18:41 PM) comp.dsp If anything goes wrong with a non air breathing high energy density battery or any high energy density energy storage material it simply becomes an explosive and there hasn't been any clever way to get aroun... Bret

The Best Name for Signal Recovery Matched Filtering 9 57 (4/19/2012 6:43:59 PM) comp.dsp I just assumed "matched filtering" included the deconvolution and other steps to recover the original signal's shape. In this case it was actually easier to invent a new filter -- I assumed it already existed ... Bret

A Few FFTs Short of MPC 31 44 (4/15/2012 3:20:20 PM) comp.dsp What has been and is being called "matched filtering" might better be called "a few steps short of complete match filtering" [which has the often desirable effect of _adding_ in some low pass filtering]. Noise... Bret

Confederacy of Dunces 30 60 (4/14/2012 8:32:26 PM) comp.dsp "When a true genius appears in the world, you many know him by this sign, that the dunces are all in confederacy against him." Jonathan Swift ... Bret

The Convolution of 2 Convolutions; More Variations on Matched Filtering 14 47 (4/12/2012 5:22:32 PM) comp.dsp In the frequency domain shift the template and multiply it by itself as well as by the noisy signal then multiply these two products together. This will result in even more attenuation of any high frequency no... Bret

You're Better Off Being A Dumb Blond 13 44 (4/11/2012 4:04:41 PM) comp.dsp You obviously want to avoid two types of errors mentioned by some philosopher, confounding two different things as one and making a distinction between two things that should be getting the same treatment. If ... Bret

Is Match Filtering Ever Used To Recover the Signal's Original Wave Form In Optics? 20 41 (4/7/2012 4:25:56 AM) comp.dsp Is it common to use matched filtering to recover the original signal in optics? Or do you always just get a convolution? Bret Cahill ... Bret

Iterative Match Filterings 60 43 (4/3/2012 5:25:33 AM) comp.dsp Instead of just taking the convolution of a signal with the reference or kernel once and then taking the square root in the frequency domain, why not match filter with the reference again and again to recover t... Bret

Anti-Cuttlefish Should Be Almost As Easy 1 55 (3/8/2012 4:36:02 PM) comp.dsp http://autos.yahoo.com/blogs/motoramic/invisible-mercedes-brings-james-bond-technology-life-171557818.html ... Bret
