Abstract:
Apparatus for generating an analog output F(x,y) according to the relationship F. sub. ij (x,y) = K. sub. 1 (a. sub. ij + b. sub. ij x) + K. sub. 2 ((c. sub. ij + d. sub. ij x) y). The coefficients and the x and y values are supplied to the appartus by a digital computer. Interpolation circuitry compares sample x and y values to select the address in the x and y arrays corresponding to the x and y sample values. An analog part of the apparatus is fed the sample x and y values and the corresponding coefficients and produces the function F(x,y).
