ASYMMETRIC SCHEDULING OF MULTIPLE ANALOG INPUTS USING A SINGLE A/D CONVERTER FOR FIBER-OPTIC TRANSCEIVERS

摘要

A firmware control method for the optimized use of a single A/D converter to measure multiple analog signals with asymmetric requirements on sampling rate including a lookup table design procedure and an acquisition algorithm. Since diagnostic analog parameter values require differing sampling rates to be effectively measured, the schedule for converting those values to digital value should correspond to the associated sampling rate. The present invention involves the creation and subsequent implementation of a scheduling table based on the required sampling rates of the operational parameters to be converted.
