<p>these specifications. The SNDR of an ADC is often summarized in terms of its <a href="page.php?w=effective_number_of_bits">effective number of bits</a> (ENOB), the number of bits of each measure it returns that are, on average, not <a href="page.php?w=Noise_%28signal_processing%29">noise</a>.  An ideal ADC has an ENOB equal to its resolution.  If an ADC operates at a sampling rate greater than twice the bandwidth of the signal, then per the <a href="page.php?w=Nyquist-Shannon_sampling_theorem">Nyquist-Shannon sampling theorem</a>, near-perfect</p><p>
