Where the article explains it
For an ADC with N effective bits resolving a full-scale reference voltage , the size of one quantization step is
The passage around this formula
…voltage , the size of one quantization step is . and, treating quantization error as uniformly distributed over one step, the resulting quantization noise power has a root-mean-square value of q / . This is the textbook derivation behind every “effective number of bits” figure a converter data sheet reports, and it is the reason oversampling helps: spreading the same quantization noise power across a wider sampled bandwidth before filtering it back down effectively lowers the…

A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
