对数回归方程 LogarithmRegress.cs 方程模型为 Y=a*LnX+b public override double[] buildFormula() 得到系数数组，存放顺序与模型系数相反，即该数组中系数的值依次是b,a。 public override double forecast(double x) 预测函数，根据模型得到预测结果。 public override double computeR2() 计算相关系数（决定系数），系数越接近1，数据越满足该模型。

There are many different (and often confusing) terms associated with clock-based devices. This application note attempts to clarify these terms, and hence serves as a comprehensive reference on clock terminology. This application note can be divided into two sections. The first section describes and distinguishes between various clock sources available today. The second section defines and distinguishes between various parameters used to describe clocks. This section also provides methods of measuring some of these parameters.

Jitter is extremely important in systems using PLL-based clock drivers. The effects of jitter range from not having any effect on system operation to rendering the system completely non-functional. This application note provides the reader with a clear understanding of jitter in high-speed systems. It introduces the reader to various kinds of jitter in high-speed systems, their causes and their effects, and methods of reducing jitter. This application note will concentrate on jitter in PLL-based frequency synthesizers.
