ABSTRACT:
Apparatus for generating an output digital signal that approximates the value of a predetermined mathematical function lying in the X-Y plane at a point defined by an input digital signal. The mathematical function is approximated by a plurality of linear least-mean-square line segments each of which includes a central point, R, and a slope, S, with the desired point being defined by the equation F(X) approximates R+S.DELTA.X, where .DELTA.X is the X distance between the central point R and the desired point. R, S and .DELTA.X are precalculated and stored in PROM lookup tables and combined as stated in the above equation.
