This application finds the periodicity of sunspots with two independent approaches

  • a frequency domain transformation of the data,
  • and autocorrelation.

If implemented and interpreted correctly, both approaches should give the same sunspot period. The application uses routines from Maple 17’s new Signal Processing package, and uses historical sunspot data from the National Geophysical Data Center. Additionally, an embedded video component demonstrates how you can zoom into a plot.
