Table 5.9 Gain in Various Numerical Bases
Let us expand our example to call for a Pre-gain of 5.15 and a Post-gain of 12.1. Using the gain formula above, the
following decimal codes are calculated:
(5.15 - 1) x 20 = 83 = Decimal code for Pre-gain
(12.1 - 1) x 20 = 222 = Decimal code for Post-gain
The conversions to binary and hex code are shown below.
