Are there any circuits that are particularly noise-sensitive These include analog-to-digital and digital-to-analog converters, video monitors, etc. This may dictate that the supply has additional filtering or may need to be synchronized to the sensitive circuit. 

The analog-to-digital converter receives the FID signals in the form of electrical voltages and converts them into binary numbers proportional to... 

Dynamic range Range determined by the number of bits in the output of the analog-to-digital converter represents the ratio between the largest and smallest signals observable in the digitized spectrum.

Fig. 14.9. Schematic representation of the analog-to-digital conversion process. The continuous analog signal output by the detector is sampled, converted into digital data points and transferred to the data system.

Both gas chromatographic instruments were connected with a PDP 11/45 computer via an analog-to-digital converter. The peak areas were calculated from the digitalized chromatographic data by means of software developed at Delft University of Technology.
