二极管钳位三电平变频器中点电压平衡相关问题研究(Diode clamped three level inverter voltage balance related problem research)

本总体方案完成国标GB20600-2006数字电视地面广播传输系统基带部分功能。 输入数据码流经过扰码器（随机化）、前向纠错编码（FEC），然后进行比特流到符号流的星座映射，再进行交织后形成基本数据块，基本数据块与系统信息组合（复用）后并经过帧体数据处理形成帧体，帧体与相应的帧头（PN序列）复接为信号帧（组帧），经过基带后处理转换为输出信号（8MHz带宽内）。该信号经变频转换为射频信号（UHF和VHF频段范围内）。用C程序设计了图形交互界面，可以在界面上直接设置调制参数。(The overall program completion GB GB20600-2006 digital terrestrial television broadcasting transmission systems baseband function. The input data stream through the scrambler (randomization), forward error correction (the FEC), then the symbol constellation mapping bitstream to the stream, and then after forming the basic block interleaving, the basic data block and information combined system ( multiplexing) after data processing and after the frame body forms a frame body, frame body with a corresponding header (PN sequence) multiplexed signal frame (framing), after post-processing baseband signal is converted to an output (internal 8MHz bandwidth). The signal is downconverted to a radio frequency signal (in the VHF and UHF frequency range). C program designed graphical interface, you can set modulation parameters directly on the screen.)

说明：  pda project using pda

foundation of fuzzy control

AVR各种应用小例程,包括各种常用传感器，液晶，步进电机，语音等等(AVR application, common sensors, LCD,stepper motor,voice, etc.)

说明：  stm32与fpga进行spi通信，fpga进行测频，占空比，时间间隔测量，32可控制其运行模式，并将测得结果于lcd上进行显示。(STM32 communicates with FPGA in spi. FPGA measures frequency, duty cycle and time interval. 32 can control its operation mode, and display the measured results on lcd)

说明：  尽管模拟高频头在开发中用得已经减少了，但是模拟电视接收功能在许多数码产品上仍有其身影。希望对本站的朋友有所帮组！(Although the analog tuner in the development of using has been reduced, but the analog TV reception capabilities in a number of digital products still has its shadow. Want to site a friend had to help group!)
