Frequency Spatial Domain Decomposition (FSDD), is an OMA modal identification algorithm in the frequency domain. FSDD an easy-to-use method. You should use it as the following steps. | |||
=====Selecting a Peak===== | |||
Press the [[Image:Modal_Manual_142.png]] button in the toolbar, and click the MIF plot to activate it. A red cross marker will appear, who is able to find the local peak automatically. The index and coordinate value of the marker are shown in the top left corner of MIF graph. In the figure below, (201,1):[32.71,-1.25e+002] means that the cross cursor is now at the 201st point of the first MIF curve, and the coordinate is (32.71Hz, -125dB). | |||
