Guest guest Posted August 6, 2004 Report Share Posted August 6, 2004 There is a fairly detailed assessment section in the s' book in which they rely pretty heavily on that spectral display (using a Procomp+/Biograph). I wonder if BioExplorer has anything comparable to this. > , > > It's a BioGraph (that I have come to love!).

Guest guest Posted August 6, 2004 Report Share Posted August 6, 2004 Ed, You are describing a Power Spectrum, which is a mainstay display of almost all training programs. BioExplorer has one which, like the BioGraph, allows you to set the range of the display, so you can see up as high as 60 Hz, where electomagnetic artifact is seen. In BioExplorer's display, you can also select the number of bins to be used in the Fast Fourier Transform, which allows you to set the resolution of the display, so you can see one Hz bands (as on Biograph) or half-hertz or tenth-hertz bands. Of course the higher the resolution, the greater the delay in the display. You can also set the bins to 64, so the range of frequencies you want to watch is divided into 64 equal-sized groups. At this resolution, the display responds so quickly (though still not actually "real-time") that it's very hard to make much from watching it. BrainMaster and Waverider software packages also have their own power spectrum displays. To the best of my knokwledge, though, BioGraph does have one very nice feature that is not readily available: it has the dominant frequency bar in a specific color, so one can easily be tracked.

Guest guest Posted August 6, 2004 Report Share Posted August 6, 2004 Do these programs allow the option to print out a copy of the power spectrum?

Guest guest Posted August 7, 2004 Report Share Posted August 7, 2004 The power spectrum display is constantly changing, like a movie, so this is like asking if you could print a single frame from a film, which of course would give you very little information about the movie. You could always pause the program in any of the ones I mentioned and then use a program like Snag-It to select and copy a JPEG of the part of the screen that contains the power spectrum to make an image of it. The Spectrogram display, available on WaveWare and BioExplorer, does allow you to visualize the display over time, at least several seconds, so it may be a more interesting one to make an image of.
