Digital representations of numerical values of quantities may BEST be described as having characteristics
Answer: D
Digital representations vary in discrete steps in proportion to the values they represent.
A digital quantity can take only a fixed set of values, so as the measured quantity changes the representation jumps from one value to the next, like the digits of a counter. A 4-bit code, for instance, has exactly 16 possible values.
Changing continuously, or varying smoothly over a continuous range or in direct proportion, describes analog representation, such as the needle of a meter or the height of mercury in a thermometer.
