Complex Demodulation Phase Plot Top Prev Next
Sample complex demodulation phase plot

  • Question:
    Is the specified demodulation frequency correct?

  • Definition:
    Vertical Axis: Phase
    Horizontal Axis: Time

  • Interpretation/Conclusion:
    The specified demodulation frequency (.30) is incorrect
    The specified demodulation frequency (.30) is too low

  • NIST/SEMATECH Handbook Chapter:
    1. Exploratory Data Analysis

  • Reference:
    Granger and Hatanaka (1964), Spectral Analysis of Economic Time Series, Princeton University Press.
