The passage around this formula
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…
