Description: The decoding algorithm used in RBDS.c is based on error trapping. The program emulates the operation of the encoder and decoder of a binary cyclic codes, using bitwise shifts and xor for modulo g(x) operations. -The decoding algorithm used in RBDS.c is ba sed on error trapping. The program emulates the operation of the encoder and decoder of a binary cyclic codes, using bitwise shifts and xor for modulo g (x) ope rations.

Description: 故障树分析 (FTA)是可靠性和安全分析的另外一种技术。1962年美国贝尔实验室为美国空军在民兵导弹发射控制系统而发展了该理论，以后被Boeing公司引进并扩展。故障树分析是许多建立在运筹学和系统可靠性之中的符号"逻辑分析方法"的其中一种方法。其他方法包括可靠性框图 ( RBDs)。
什么是故障树图 (FTD)?
故障树图 ( 或者负分析树)是一种逻辑因果关系图，它根据元部件状态(基本事件)来显示系统的状态 (顶事件)。就像可靠性框图 (RBDs)，故障树图也是一种图形化设计方法，并且作为可靠性框图的一种可替代的方法。

Description: RDS(Radio Data System)数据广播系统是将数字信号调制到调频波段
(87.5~108MHz)并以广播的形式发送的一种信号传输系统。这种传输模式在北美
和欧洲得到了采用，而且得到越来越多的其他国家的关注。在北美和欧洲 都有
相应的标准，即RBDS 和RDS。
传输数据时，数据加载到57KHz 的副载波频段。副载波经过调制以适应固定
的双相编码信号。这个副载波经过抑制以避免调制后的数据在锁相环立体声解码
器中产生混叠同时还要与德国同样采用57KHz 频率作为副载波的ARI 系统保持
兼容。发送的信号以组(group)为单位，每组信息包括4 块(block),每块信息包
括26 位，分别为16 位有效信息和10 位校验信息。整个系统包括32 种不同的
组，分别代表不同的信息。在发送过程中，电台根据需要发送不同的组以及不同
的组合以达到发送不同信息的目的。然而PI、PTY 和TP 信息在每组信息都有包
含。-RDS (Radio Data System) data broadcasting system is modulated digital signal to the FM band
(87.5 ~ 108MHz) and send the form of broadcasting a signal transmission system. This transfer mode in North America
And Europe have been used, but more and more the concern of other countries. In North America and Europe have
Corresponding standards, RBDS and RDS.
Transmit data when the data is loaded into the 57kHz subcarrier band. Subcarrier modulated to adapt to a fixed
Dual-phase encoded signals. The sub-carrier after suppression to avoid the modulated data in the phase-locked loop stereo decoder
Device aliasing while 57kHz frequency as the subcarrier of the ARI system remains the same with Germany
Compatible. Send a signal to the group (group), each including 4 (block), each packet
Including 26, 16 information and 10 parity information. The entire system, including 32 different
Group, representing different information. In the sending process, the radio need to send different group
