along with the development of digital technology,digital filters are widely used in many fields,this paper introduces how to design a iir digital notch filters in matlab environment.the design of digital notch filters can be achieved through three steps:firstly,the design of analog lowpass filter; secondly,it is analog lowpass to analog band stop filter conversion;at last,using the bilinear transformation make the analog notch filters change into digital notch filters.the paper also introduces how to design the transfer function of the digital notch filters using all the zeros and farthest points at the same time,it also introduces the program of the digital notch filters under butterworth analog lowpass prototype.

摘 要：随着数字技术的发展，数字滤波器在许多领域得到广泛的应用。研究一种在matlab语言环境下设计iir数字陷波滤波器的方法，在数字陷波滤波器设计过程中，先进行模拟低通滤波器的设计，然后进行模拟低通/模拟带阻滤波器转换，最后采用双线性变化法将模拟陷波滤波器转化成数字陷波滤波器。提出一种用所有零点和极点来表达数字陷波器传递函数的方法，同时给出以巴特沃斯模拟低通为原型设计数字陷波滤波器的程序。关键词：无限冲激响应；巴特沃斯滤波器；数字陷波滤波器；matlab；双线性变换

No, I don't like to boogie.

但我不并喜欢在这里跳舞，我呆住在那，动也不能动，这真是糟到极点。

With the help of the optimization theory, we present the vertex solution theorem for determining both the exact upper bounds or maximum values and the exact lower bounds or minimum values of the dynamic response of structures, in which these parameters reach their extreme values on the boundary of the interval mass, damping, stiffness matrices and the interval external loads vector.

Assignment of infinite many poles for the first order generalized distributed parameter control system, coupled with the first order generalized lumped parameter control system, is discussed in Hilbert space with functional analysis and operator theory. The solutions with the constructive expression are given by the generalized inverse one of bounded linear operator.

This indicates that it is impossible to design a Clarke-Gawthroptype self-tuning controller or an adaptive pole placement controller for unknown nonminimumphase plants to track arbitrary bounded set point sequences asymptotically.

这表明对未知离散非最小相位系统，不可能设计Clarke－Gawthrop型自校正控制器或自适应极点配置控制器去渐近跟踪任意有界设定序列。

He was so brimful of exultation that he could hardly hold himself when the old lady came back and stood above the wreck discharging lightnings of wrath from over her spectacles.

当老太太走进来，站在那儿望着地上的破碎的罐子，从眼镜上面放射出愤怒的火花，他真是高兴到了极点，几乎按捺不住了。

The modeling method of valve components is based on the impedance measurements. Vector fitting is used to approximate the rational functions and Brune method is applied to provide equivalent circuits suitable for EMTP or PSCAD.

其中，阀组件内各元件的阻抗通过网络分析仪测量，然后通过矢量匹配进行零极点提取，最后通过布隆法进行网络综合得到阀组件各器件的宽频等效电路。

A city man is "split" in the present society to the last degree, as it were, which is growing more and more visible as modernization ploughs forward, while a "bucolic" and "complete" man is heading for extinction gradually.

都市人的"分裂性"在这个社会中可以说是达到了一个极点，随着现代化的进程的开进，这种都市人的"分裂性"会表现的越来越明显，而那种"田园性"的"整一性"的人却在慢慢的成为"濒危物种"。

Then the noise transfer function is realized by optimized zero and Butterworth poles.
