Publisher review:2-sided Zmod shows a bi-directional spectrogram of a whirling shaft. Rotating shafts experience a an elliptical motion called whirl. It is important to decompose this motion into a forward and backward whil orbits. The current function makes use of two sensors to generate a bi-directional spectrogram. The method can be extended to any time-frequency distributioncompute the forward/backward Campbell/specgtrogramINPUT:y (n x 2) each column is measured from a different sensor__|s1| y(:,1)|__|__/ ________|/| | | s2 |/ y(:,2)____/ --------|/Fs Sampling frequnecyOUTPUT:B spectrogram/Campbel diagramx x-axis coordinate vector (time or Speed)y y-axis coordinate vector (frequency [Hz]) Requirements: · MATLAB Release: R11 · Signal Processing Toolbox
