7.3增量总和(△-)调制 1.简单增量调制的缺陷临界过载条件:f△=Ax与信号频率有关;信号频率越高,越容易产生过载; 2.增量总和(△-)△M基本原理编码时,对信号作“积分”变换:A(a)>A()/jo临界过载条件:(A(a)/jo)->A(a),仅由信号幅度确定,与信号频率“无关”解码时,对信号作相反的(“微分”)变换,恢复原信号

1 The Number-Picking Game Here is a game that you and I could play that reveals a strange property of expectation. 3, First, you think of a probability density function on the natural numbers. Your distri- bution can be absolutely anything you like. For example, you might choose a uniform distribution on 1, 2, ... 6, like the outcome of a fair die roll. Or you might choose a bi- probability, provided that,...,n. You can even give every natural number a non-zero nomial distribution on 0, 1 he sum of all probabilities is 1

本文在文[2]的基础上,对系统$\\left\\{ {_{\\frac{{{\\rm{dy}}}}{{{\\rm{dt}}}}{\\rm{ = a - }}{{\\rm{x}}^{\\rm{2}}}{\\rm{y}}}^{\\frac{{{\\rm{dx}}}}{{{\\rm{dt}}}}{\\rm{ = b - }}{{\\rm{x}}^{\\rm{2}}}{\\rm{y}}}} \\right.\\;\\;\\;\\;\\;\\;\\;(1)$（其中a>0,b>0）作了更深入的研究,从而得到当a-b≤（a+b）3时,系统（1）无极限环的结论,并指出了,当a-b>（a+b）3时,系统（1）的极限环的位置及其随参数a,b的变化情况
