摘要
介绍了几种基于数字信号处理器(DSP)的正弦波产生法,给出了这些产生正弦信号的算法和主要源程序代码或流程,同时给出了TMS320VC5402 DSP与D/A转换器TLC320AD50C的接口电路.经过程序的实际运行,得出了软件仿真和硬件仿真所得的正弦波形.最后,分析了各种方法的优缺点,讨论了调整输出信号频率的方法.
It introduced several methods for generating sine wave Processor（DSP）. The main source programs of these methods were given, based on Digital Signal and the hardware circuit of interface between TMS320C5402 DSP and Digital to Analogue （D/A） inverter TLC320AD50C was given in the meantime. Then sine waves from simulation and emulation were also shown. At last, advantages and disadvantages of these methods were analyzed and adjusting frequency method was discussed.
