    Discarding signal phase information can lead to errors, as identical magnitude spectra can arise from different signals. This study demonstrates that incorporating phase information in discriminant analysis improves signal differentiation, particularly for spinal cord evoked potentials.

    Area of Science:

    • Signal processing
    • Biomedical engineering
    • Neuroscience

    Background:

    • Magnitude spectra are often used alone in signal processing, neglecting crucial phase information.
    • Phase information is essential as different time-domain signals can share identical magnitude spectra.
    • Neglecting phase can lead to misclassification in discriminant analysis.

    Purpose of the Study:

    • To investigate the utility of incorporating phase information into discriminant analysis.
    • To develop and test a discriminant analysis procedure for paired magnitude and phase variables.
    • To apply this procedure to differentiate between normal and damaged spinal cord somatic evoked potentials.

    Main Methods:

    • A simulation study was conducted to evaluate a novel discriminant analysis procedure.

  • The procedure was designed to analyze paired magnitude and phase data from signals.
  • The method was applied to real-world data of somatic evoked potentials.

    • Main Results:

    • The simulation demonstrated the effectiveness of the proposed discriminant analysis method.
    • The procedure successfully discriminated between somatic evoked potentials from normal and damaged spinal cords.
    • Excellent results were achieved in classifying the evoked potentials.

    Conclusions:

    • Phase information is critical and should not be neglected in signal processing and discriminant analysis.
    • The developed discriminant analysis procedure effectively utilizes both magnitude and phase for improved signal differentiation.
    • This approach shows significant promise for diagnosing spinal cord conditions based on evoked potentials.
