Quantization efficiency

The Analog-to-Digical-Converter (ADC) will quantize the analog signal on a finite number of bits. This can be seen as an additional source of noise that is modeled as a spectrometer efficiency ( \ensuremath{\eta_\ensuremath{\mathrm{spec}}}) and Eq. 2 becomes

\begin{displaymath}
\ensuremath{\sigma_\ensuremath{\mathrm{K}}} = \frac{\ensure...
...emath{d\nu}\,\ensuremath{\Delta t_\ensuremath{\mathrm{}}}}}.
\end{displaymath} (3)
