C)resolution
D)common mode rejection ratio

Question

Quizplus · Accepted Answer

The resolution of an analog I/O module specifies how accurately an analog value can be represented digitally. It is typically measured in bits (e.g. 16-bit resolution) and indicates the number of discrete levels that can be detected and reported by the system. A higher resolution means a more accurate representation of the analog input signal. The number of inputs and outputs, input impedance and capacitance, and common mode rejection ratio are all important specifications for an analog I/O module, but they do not directly relate to the accuracy of digital representation.
