Abstract
A signal conversion system parses a multi-dimensional input signal into most-significant and least-significant portions. The most-significant portions are used as an index to a look-up-table. Stored in each entry of the look-up-table is a base value and multi-dimensional differential values. The system generates an output representation of the signal by combining the corresponding base value with interpolated differences determined by interpolation performed using the differential values and the least-significant portions. Interpolation error is decreased by storing intermediate differential values. Output processing is used for linearization.
