Well, it's a FACT that N bits represents just so many integer values...that
the number of bits is directly related to the number of values that can be
represented. That, in and of it self, IS a resolution. 8 bits can
represent only 256 values, so 256:1...or a dynamic range of 48dB...

But dynamic range DOES denote a resolution of the system.
