Notes:
1. R' > 10k
2. Consideration for the value of R is LVDT loading.
3. RMS values given.
4. Use the absolute values of Va and Vb when subtracting per the formula for
calculating resistance values, and then use the calculated sign of "Va and Vb"
for calculating SIN and COS. The calculations shown are based upon full scale
travel being to the Va side of the LVDT.
5. See the RDC application manual for calculation examples.
6. Negative voltages are 180 phase from the reference
