3) See thin film network DDC-55688-1.
R1 + R2
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.
Notes:
1) Resistors selected to limit Vref peak to between 1 V and 5 V.
2) External reference LO is grounded, then R3 and R4 are not
needed, and -R is connected to GND.
