基于DDS的信号源设计（包括三角波、正弦波、方波）(Design of signal source based on DDS)

标准RS422 Verilog源代码， 传输波特率可以修改， FPGA上可以工作(Standard RS422 verilog communication source code, buardrate can be updated and it is fully work in FPGA )

能够完美产生数字地面电视（DTMB）的信源的程序。帧头模式为模式一。信道可选择，信号加入频偏，延时，后经滤波器后输出。(Able to produce perfect digital terrestrial television (DTMB) of the source program. Mode is the mode a header. Channels to choose from, the signal adding offset, delay, after the filter output.)

与单片机相比，用CPLD/FPGA器件更适合于直接对高速AD采样控制。本实验接口器件为ADC0809，根据ADC0809的工作时序使用CPLD产生该控制信号，CPLD启动AD转换后，得到的数据送至单片机并在PC机及数码管上显示AD转换结果。(Compared with the microcontroller, CPLD/FPGA devices more suitable for direct sampling control of high-speed AD. The interface of the experimental device for the ADC0809 ADC0809 Timing CPLD is used to generate the control signal, the CPLD to start the AD conversion, the data sent to the microcontroller and the AD conversion result on the PC and digital tube display)

FPGA来实现数据采集，AD采用TI公司的THS1206，高速并行AD，内含16字FIFO，降低硬件复杂度。(FPGA to realize data acquisition, AD using TI company s THS1206, high-speed parallel AD, containing the 16-character FIFO, to reduce hardware complexity.)

频率计 测量范围1-100MHz 测量阈值0.1s 计数部分为FPGA/CPLD 语言VHDL 显示部分为51 单片机加八位数码管 语言C(Frequency meter Measuring range 1-100 MHZ Measure threshold is 0.1 s Count part of FPGA/CPLD Language VHDL Display part of 51 MCU with eight digital tube Language C)

this the for a equiripple filter-this is the for a equiripple filter
