dynamic range
In electronic circuitry, certain passive but especially active electronic components such as diodes, thyristors and transistors can only be controlled with a certain maximum permissible voltage or current.
If the control voltage exceeds the linear modulation range, the corresponding component or quadripole operates in the non-linear range, which leads to distortions of the signal shape. Within the dynamic range is the operating point, which is located on a characteristic curve or a set of characteristic curves.
