摘要
介绍了基于直接数字频率合成(DDS)技术的内置式计算机干扰器系统,该系统以单片机为控制核心,将蒙特卡洛算法产生的伪随机序列,写入数字化、可编程的DDS芯片作为控制字,实现输出的噪声调制。
This paper introduces the built -in computer interfering system based on Direct Digital frequency Synthesizer （DDS） technology. This system regards single -chip as control core, writes the pseudo random array produced by the algorithm of Monte Carlo into the digital and programmable DDS chip as control words. Finally it realizes the noise modulation from the DDS export Signal.
