commanded. The constant of proportionality is
0.33% of the decibel gain commanded, per degree
Celsius, referenced to 27°C (300°K). This means that
at 0 dB gain, there is no change in gain with tempera-
ture. However, at -122 mV, the gain will be +20 dB
at room temperature, but will be 20.66 dB at a
temperature 10°C lower.
