CORDIC
- 数字控制振荡器（NCO，numerical controlled oscillator）是软件无线电、直接数据频 率合成器（DDS，Direct digital synthesizer）、快速傅立叶变换（FFT，Fast Fourier Transform） 等的重要组成部分，同时也是决定其性能的主要因素之一，随着芯片集成度的提高、在信号 处理、数字通信领域、调制解调、变频调速、制导控制、电力电子等方面得到越来越广泛的 应用。-Digital controlled oscilla

- 数字基带信号的传输是数字通信系统的重要组成部分。在数字通信中，有些场合可不经过载波调制和解调过程，而对基带信号进行直接传输。采用AMI码的信号交替反转，有可能出现四连零现象，这不利于接收端的定时信号提取。而HDB3码因其无直流成份、低频成份少和连0个数最多不超过三个等特点，而对定时信号的恢复十分有利，并已成为CCITT协会推荐使用的基带传输码型之一。为此，本文利用VHDL语言对数据传输系统中的HDB3编码器进行了设计。 基于达到达到达到的信号发生器的源程序-Digital baseband
