Abstract
A quotient (y −y )/(y −y ) is generated by circuitry where Y are asynchronous samples from a sequence of asynchronous samples, the quotient (y −y )/(y −y ) is compared to a plurality of predetermined fractions with a comparator, and an initial interpolation interval value (&mgr;0) stored in a lookup table is selected by circuitry based on the comparison of the quotient to the plurality of predetermined fractions. The predetermined fractions can represent boundary points and the quotient can fall between an interval defined by two of the boundary points. The selected initial interpolation value (&mgr;0) can be the average of two calculated values of (&mgr;) using values of two predetermined fractions associated with the two boundary points between which the quotient falls.
