摘要
证明了应用数字积分法插补直线和圆弧时误差与脉冲当量的关系:直线插补时,首次提出应用严格的不等式证明方法,证明其插补误差不超过一个脉冲当量;圆弧插补时,应用反证法,证明其插补误差有可能超过一个脉冲当量.
The Interpolation principle of digital differential analyzer is described in a nutshell. The relationship between error and pulse- equivalent is proved when lines and arcs are interpolated by this method. The error can't exceed one pulse - equivalent when interpolating line, which is certified by mathematical derivation. The error can exceed one pulse - equivalent when interpolating arc, which is certified by reduction to absurdity.
