This leads to the following quantized value, which is very close
to the desired value of 6.98672x10
CALCULATION OF THE REGISTER VALUES
The quantized coefficient consists of two components,
where

two-step process.
Using the example value of − = 7.50373 × 10
This leads to the following quantized value, which is very close
to the desired value of 7.50373x10
