Hi, what's the book and the paper name? Thanks.
 

Hi,

For 2 bits output, the ADC gives the sign bit and the second bit is MAG bit whch is made high for 30% of the time. You may refer pless, Philsar (formerly) chip specifications for this.

For higher number of bits there seems no clear definition. TI uses 4 bits. But the quantization levels are not clearly defined with respect to others. So it is normally defeined with respect to the baseband processing.
