I didn't know that resolutions are defined in volts until today. I never wrote units to them. I read in wiki that...
So it can be expressed as both? I'm confused. Must I write units to resolution, or can I interchange them between bits and volts?
Resolution
Fig. 1. An 8-level ADC coding scheme.The resolution of the converter indicates the number of discrete values it can produce over the range of analog values. The values are usually stored electronically in binary form, so the resolution is usually expressed in bits. In consequence, the number of discrete values available, or "levels", is a power of two. For example, an ADC with a resolution of 8 bits can encode an analog input to one in 256 different levels, since 28 = 256. The values can represent the ranges from 0 to 255 (i.e. unsigned integer) or from −128 to 127 (i.e. signed integer), depending on the application.
Resolution can also be defined electrically, and expressed in volts. The minimum change in voltage required to guarantee a change in the output code level is called the least significant bit (LSB) voltage.
