基于DSP builder搭建的DDS模块，可以用在数字下变频中的NCO等-Based on DSP builder to build the DDS module can be used in digital down-conversion of the NCO, etc.

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

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

利用Altera公司推出的FPGA开发工具DSP Builder，对锁相解调算法中的主要部件：数控振荡器(NCO)、计算反正切的CORDIC模块和FIR低通滤波器进行了单独设计和仿真，最终完成了锁相解调系统的整体设计。-Designed and simulated major components of phase-locking Demodulation Algorithm independently, including: Number Controlled Oscillator(NCO)、
