多进制数字频率调制(MFSK)系统VHDL程序

使用verilog语言描述的二阶巴特沃斯IIR滤波器，程序中有参数说明，已经运行通过(Using verilog language to describe the second-order Butterworth IIR filter, the program has parameter description has been run through)

ppm调制的verilog代码 可实现ppm调制(ppm modulation verilog code ppm modulation)

说明：  Use of Kalman and EKF on two-phase permanent magnet synchronous motor of the state estimate CDCDCDCDCCC

改VHDL代码可以实现超声波测距的功能，其精确度达到US级，可以用七段数码管显示其数值(sound ranging sound ranging sound ranging sound ranging sound ranging sound ranging sound ranging sound ranging sound ranging sound ranging sound ranging )

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.)

用VHDL编写的EPP通信协议，可以同时收发字节-EPP written in VHDL, communication protocol, you can also send and receive bytes

在FPGA EGO1的口袋平台上实现数码管滚动显示学号的功能(Rolling on the digital tube to display the school number)

16位浮点FFT算法的VHDL实现有测试文件！-16-bit floating-point FFT algorithm VHDL realization of a test file!

VHDL库，仿真时使用的，包括打印，类型转换等实用的操作(Practical operation VHDL library, using simulation, including print, type conversion, etc.)

NiosII的C代码,包括网卡,lcd,usb,串口,按键.(NiosII C code, including network cards, lcd, usb, serial, key.)
