摘　　要：针对模/数(A/D)及数/模(D/A)转换器的线性误差,分析了A/D,D/A转换器转换特性之最佳拟合直线的几何特征,提出了用几何图形搜索法确定最佳拟合直线的算法,讨论了算法原理,并给出了算法框图,该算法速度快、精度高,既适于人工计算又适于电子计算机处理。For the linear error of A/D and D/A converters, the geometrical features ofthe best fitting line of A/D and D/A converters, converting characteristics is ana-lyzed and an algorithm using the method of geometrical graphic searching to decidethe best fitting line is presented. This algorithm has the advantage of high speedand satisfactory accuracy, and is suitable for both manual calculation and computerprocess. The principle of this algorithm is discussed and its block diagram is pro-vided.
