Time FFT statistics

Time FFT  gives you many information about the changes in signals frequency domain, and it is sometimes very useful to summarize that information. Time FFT statistics enables you to divide Time FFT result into different frequency segments and to calculate, display and transfer summarized statistics reports to other programs.

By choosing 3D Tools/Time FFT statistics from menu, a dialog for statistics data display will appear. On the left side,  5 pairs of edit-boxes (From - To) are available which show 5 possible frequency segments. You can enter segments boundaries here and press Calculate button.

The calculation report will appear in big edit-box showing you max, min, sum, avg. values for each segment. By pressing Clipboard button, the complete report will be transferred to clipboard, so you can transfer it to some word processing program or Microsoft Excel.
If you use Time FFT statistic often, you can create templates for segments that you use, so you would not have to type them every time. You can do it by creating (or editing existing one) file called TFFTSTAT.RNG in SIGVIEW's application data directory (usually C:\Documents and Settings\<UserName>\Application Data\Sigview\). This file has the following structure:

where each row in a file represent a new template, fromX, toX are segment boundaries, NameX is name of template which will appear in template combo-box. Initially, this file has only one row which represent an empty template.

You can edit this file with any text editor.

If the file exists, its first row will be used as a default template as soon as you open Time FFT statistics window. Afterwards, you can switch to other templates by choosing them from Template combo-box.
