  • Measuring and analyzing biological signals is crucial for understanding these mechanisms.
  • Spectrum analysis is a conventional method for signal analysis.

Purpose of the Study:

  • To discuss the significance of spectrum analysis for biological signals.
  • To connect spectrum analysis with linear system identification in biological contexts.
  • To briefly mention Wiener analysis for non-linear biological systems.

Main Methods:

  • Signal measurement from biological systems.
  • Application of spectrum analysis techniques.
  • Exploration of linear system identification principles.

Related Experiment Videos

  • Consideration of Wiener analysis for non-linear systems.
