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).
