• maybe add vertical line at werever amplitude = 1 for the hilbert plot? Woud make it easier to spot the actual phase angle associated with maximum aplitude
• Hilbert transform instead of "Hilbert function"

[lakimenon]

Typos:

• "smalller" in the second point under the Simulated PAC signal image
• "thes" instead of "these" in the last line before part 2
• Under Phase and Amplitude of ECoG signal graph, it says "it's possible a positive correlation between these two measures." - maybe should be "...correlation exists between..."
• Under "Determine the strength of the correlation..." : "yield" is misspelled as "yeild" towards the end
• "historgram" under "Visualize coupled phase"
• "realtionship" towards end of second paragraph in summary

Other comments:

• Under the polar graph, it says that amplitude is steadily increasing around 135-180. This could be misleading as there is a general increase between 90 and 225, but it actually appears to be decreasing strictly between 135-180.

  • Code may need more comments?
    • What does nyquist frequency mean? Is that a term I should already be familiar with? Or will it be explained in the tutorial linked above?
  • What is the Hilbert function/transform? When the Butterworth function was introduced in tutorial 2, there was a more detailed explanation (with what it’s useful for, parameters, why we use it, etc…. )
