Reflection Series Vs No Reflection Series Analysis
1. Model wavelet with reflection series included as non-white component.
Note that the result appears to be negative polarity though the input polarity was positive.
2. Model wavelet with no reflection series. Note the approximate 90 degree phase shift.
3. Phase-only inverse of 1 applied to 2.
4. Phase plot of 3. Above. Amp Scale and Time Scale annotation are artifacts of the time series wavelet viewer. Ordinate is Phase in degrees and Abcissa is frequency in Hertz. Note the approximate 50 degree constant phase shift produced.
Scripts used to produce above analysis.
Reflection Included Script-Produces 1. Above.
