用DSM调制1-bit输出，经简单模拟滤波电路，产生VGA控制电压。对于内部频率高、但VGA变化速度较慢的场合，可以达到很高的控制精度，从而省却了内部高精度DAC的模块(DSM modulation with 1-bit output, through a simple analog filter circuit, producing VGA control voltage. in the circumstance of high internal frequency, but need a slower changing VGA control, this program can achieve high control precision, and thus save the internal high-accuracy DAC module)

从初值出发，先计算y对时间t的导数，得到y的变化速度；求出x对t的导数，得到x随时间的变化速度。然后时间前进一小步h=0.002，同时x和y也都发生一个小的变化，即在原来数值基础上加上时间步长h和变化速度的乘积。如果x到达1或者-1，强制让y发生变化。这个过程不断迭代，得到结果。 (completed chart)
