An interpolator forN-TH-order curves

A method is presented that allows to generate curves of any order; it can be implemented with a very simple interpolator circuit—making use of counters and adders only—or can be used for writing a computer program. The interpolation is fast and accurate, the error (i.e. the distance of the approximated curve from the ideal) being limited and depending solely on the interpolation step. In particular, an interpolator for cubic curves is described.
