NOTES: A. Vuse _(typ) is defined as the voltage determined to equal the camera white clip. This voltage must be less than Vuse _(max).
B. A system trade-off is necessary to determine the system light sensitivity versus the signal/noise ratio. By lowering the Vuse _(typ),
the light sensitivity of the camera is increased; however, this sacrifices the signal/noise ratio of the camera.
