I am investigating the synchrony of multiple oscillations and I am struggling to identify the upper/lower frequencies relative to the half maximum.
Could anyone suggest a simple way to:
- Identify the peak amplitude of an oscillation in a frequency range.
- Calculate 50% of this peak amplitude.
- Identify upper and lower amplitude values at 50%.
- Determine the corresponding frequency of the upper and lower 50% values.
Any help would be greatly appreciated!
