7. Apply the Ellipse Method to observe the phase difference between the two channels.
Signal in X-Y Format:
Instruction of the Ellipse Method
Sinθ = A/B or C/D, where θ = phase shift (in degrees) between the two signals.
From the formula above:
θ = _arcsine (A/B) or _arcsine (C/D)
θ must be in the range of (0~π/2) or (3π/2~2π) if the main axis of the ellipse is between I and III
quadrant, . If the main axis is at II and IV quadrant, θ must be in the range of (π/2~π) or (π~3π/2).
