Switched Capacitor Network Analysis by Means of TCM

The totally coded method (TCM) reveals the same objective law, which governs the gain calculating for signal flow graph as Mason formula does. This algorithm is carried out merely in the domain of code operation. Based on pure code algorithm, it is more efficient because figure searching is no longer necessary. The code-series (CS), which are organized from node association table, have the holoinformation nature, so that both the content and the sign of each gain-term can be determined via the coded method. The principle of this method is obvious and it is suited for computer programming. The capability of the computeraided analysis for Switched Capacitor (SCN) can be enhanced.

On the Performance of Punctured Turbo Codes

IntroductionTurbo codes, first introduced by Berrou et al.[1],have attracted the attention of many researchers for theirremarkable coding gains close to theoretical limits, yetadmitting a relatively simple iterative decodingtechnique[2]. Since then, abundant of fruitful results on theperformance of turbo codes have been published, in whicha distance spectrum interpretation was presented by [3]and a super trellis structure of turbo codes was derived by[4]. An analytical…     

人格与家教——《傲慢与偏见》与《小妇人》之比较

《傲慢与偏见》与《小妇人》 ,两部作品虽然描写的都是儿女情长 ,但侧重点不同 ,前者在描写爱情故事的同时 ,揭露了资产阶级婚姻制度的本质 ,后者则偏重于对个性独立 ,自我约束的描写 ,突出人格完善的重要性。从对两部小说的对比可发现家庭教育对人格形成起着重要的作用 ,而不同的人格结构会造就出不同的价值观和人生观。
