Method for generating quadratic curve signal

摘要

Assuming that a given equation representing a quadratic curve is: F(x, y)=ax2+bxy+cy2+dx+ey+f=0, the method for generating quadratic curve signals repeatedly selects a point close to F (x, y)=0 in only one of either the region of F (x,y)>/=0 or the region of F (x,y)<0. This method allows to generate quadratic curve signals by using only a few parameters and without using complicated calculations. A hardware implementation is also disclosed.
