Figure 2

A spectrum screen in LabChart in which the power of each frequency domain (ms2) is calculated. The very low frequency (VLF), low frequency (LF), and high frequency (HF) domains are indicated in the figure. The solid red line in the figure represents the power calculated in each frequency band by spectral analysis.
