Abstract
A method, comprising: selecting two Two-Tuples before and two after a selected synchronous ADC conversion point; calculating the coefficients of a third order polynomial based on the value of the previous time asynchronous sample, the time differences between each of the asynchronous samples surrounding the selected sample, and the three linear slopes of the line segments between the two points before and the points after the selected synchronous sample point, including the slope of the selected point; evaluating the third order polynomial at the synchronous time instant; generating the synchronous ADC value based on this calculation; and using the ADC value as the desired voltage level of the synchronous sample, wherein the synchronous ADC value is generated based on this calculation.
