Hover the mouse over these fields to see the exact percentages.
On the upper right side of the page, the "Signal quality"
percentage shows the lowest quality rating obtained across all 4

If the signal quality is poor, the validity of the overall recording
should be questioned.

signal quality will increase and study will be considerably improved.
