A B

Picture 3-3

Sin θ=A/B or C/D where θ=phase shift (in degrees )between the two signals

From the formula above ,you could get:

θ=±arcsine (A/B) or ±arcsine (C/D)

If the main axis of the ellipse is at Ⅰ and Ⅲ quadrant , θ must be in the range

of (0～π/2) or (3π/2～2π).if the main axis is at and quadrant, θⅠ Ⅲ must be

in the range of (π/2～π) or (π～3π/2).

The signal must be medical

horizontal
