I am using the AD2S1210 for the Tamagawa resolver.
I would like to know the impact of the cos/sin wobbling on the AD2S1210 angle and speed tracking performance.
As you can see in the attached screenshot, the blue is cosine and the green is sine.
Peaks of cosine and sine keep changing and the speed obtained from the AD2S1210 has a periodic ripple aligned with rotation frequency.
Is it an expected result?
