The following example is chosen to illustrate all aspects of this procedure.
1.
QUADRATURE input
2.
1 decimal place
3.
A = 3
targets per rotation
4.
Gearbox ratio 4.7 to 2
B = 4.7
C = 2
5.
D = 4
Numerator = 2
Denominator = 3 x 4 x 4.7 = 56.4
6.
Multiply both by 10 to eliminate decimal in denominator
Numerator = 2 x 10
= 20
Denominator = 56.4 x 10
= 564
7.
Format
Numerator = +020.0
Denominator = 0564
8.

Note: 20/564 = 0.0354609929078014 to 16 decimal places. The ratio ensures no precision
is lost.
