NOAA/ OERD T-Phase Project: Signal Analysis

T-Phase Signal Analysis is one of major operations for the 2 T-Phase data processing programs. Signal Analysis is used mainly for the Biological Signals. When it is activated from the main manual, it allows users to select a range of displayed signal from the main window and redisplay the data spectrum in a higher resolution by redefine the specturm sample rates. Users may choose a predefined T-Phase recording sequence, point and click on the sub-window to identify and record the signals. Users have the option to save the results into an output file.

The picture shows a refined spectrum were diplayed in a sub-window located at the upper right. The upper left corner of the picture shows the selected data range. Its data signals were plotted on the display area of Signal Analysis manual.

The other major operations for the T-Phase programs are Locate a T-Phase event's origin and identify T-Phase signals by mathematical filters.
