Digital Equivalents Definition

[Varenthal]

Hi, I am trying, (in vain it seems) to find a definition of what digital equivalents are. It would be in terms of the relation of digital equivalents to f-stops/T-stops. Any help in pointing me to any place that has a clear and simple definition is greatly appreciated.

Since digital cameras use F-Stops the same as optical cameras, and adjust exposure time the same as film cameras, F-Stops and T-Stops are the same. ISO is even the same since it represents the sensitivity of the surface (film or CCD array) to light.

Maybe if you could better explain what you believe are the differences?
