R1 + R2 X Volt
R1 + R2 should not load the Resolver too much; it is recommended to use a R2 = 10k.
R1 + R2 Ratio Errors will result in Angular Errors,
2 cycle, 0.1% Ratio Error = 0.029° Peak Error.
Note: The five external BW components as
shown in FIGURE 1 and 2 are necessary
for the R/D to function.
