turbo码搭建了简单的系统来进行纠错展示,可以实现从编码,加入错误,译码,输入输出码字对比等基本功能,另外加入了交互模块,用户可以自己设定错误比特的数目和位置,使纠错功能显而易见.-turbo codes built a simple system for correcting display, from coding can be achieved by adding errors, Decoding, input and output code contrast basic functions, adding to its interactive modules, Users can set their own errors and the number of bits, so that error-correcting functions obvious.

三点式振荡器是指LC回路的三个端点与晶体管的三个电极分别连接而成的电路，如图4-1（a）所示。图中三个电抗元件X1、X2、X3构成了决定振荡频率的并联谐振回路，同时也构成了正反馈所需的反馈网络。从相位条件看，要构成振荡器，必须满足： (1)极相连的两个电抗X1、X2性质相同。 (2)X1与X2、X3的电抗性质相反。-three-point refers to LC oscillator circuit with three transistors endpoint of three electrodes were connected with the circuit, Figure 4-1 (a) below. Figure 3 reactor components X1, X2, X3 decision constitutes a frequency of the oscillation parallel resonant circuit, but also constitutes a positive feedback for the feedback network. From Phase conditions, to constitute an oscillator, to be met : (a) very connected to the two reactor X1, X2 the same nature. (2) X1 and X2, X3 nature of the resistance-- contrary.
