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 Motivation The Poisson problem has a strong formulation a minimization formulation and a weak formulation T weak formulations are more general than the strong formulation in terms of regularity and admissible data SLIDE 2 The minimization/weak formulations are defined by: a space X; a bilinear The minimization/weak formulations identify ESSENTIAL boundary conditions NATURAL boundary conditions ed in a The points of departure for the finite element method are the weak formulation(more generally) the minimization statement (if a is SPD) 2 The dirichlet problem 2.1 Strong Formulation Find u such that

1.设a为有理数,x为无理数,证明: (1)a+x是无理数(2)当a≠0时,ax是无理数.证:(1)假设a+x是有理数,则(a+x)-a=x是有理数这与题设x是无理数相矛盾,故a+x是无理数

say it just begins to live that day. Emily Dickinson, \A Word\ A particular string of sounds must be united with a meaning and a meaning must be united with specific sounds in order for the sounds or the meaning to be a word in our mental lexicon. A word, then, is a free form which does not consist entirely of (2/3) lesser free forms; in brief
