dspddc_R12p1
- 基于DSPbuilder搭建的DDC，里面包括CIC滤波器，FIR低通滤波器，HB半带滤波器，NCO等，实现了GC5016芯片的功能-DSPbuilder erected based on DDC, which include the CIC filter, FIR low-pass filter, HB half-band filter, NCO, etc. to achieve the function of the GC5016 chip
nco
- 一个NCO的定点数模型，结构完整，功能正确。是用DSP BUILDER做的，自己做的-NCO of the fixed points of a model, structural integrity and function correctly. DSP BUILDER is done, do their own

- 在EDA实验课上面，自己编写的NCO程序，可以产生出比较真实的正弦波、三角波以及锯齿波，用VHDL程序编写，有modelsim仿真textbench程序-On EDA experiment, oneself write the NCO program, can produce more real sine wave, triangular wave and sawtooth wave with VHDL programming, have the modelsim simulation text
DDC
- matlab 编写的简单数字下变频仿真程序，含NCO模块、混频、低通滤波、抽取。模块大多采用matlab自带函数实现- program for DDC simulink base on Matlab
DDC
- nco + cic + ddc 数字下变频抽取滤波的基础步骤，代码已通过调试-nco+ cic+ ddc
