摘要
针对FPGA在做普通DDS波形合成时带宽会受到工作时钟限制的问题,介绍了可以合成高速率、大带宽的多相结构波形合成方法。给出了该方法的工作原理和具体实现方式。通过仿真分析证明,该波形合成方法能够合成频谱质量较好的正弦波形和调频波。
To solve the problem of the constraint on the bandwidth of DDS based on FPGA,this paper introduces a high-speed,wide-bandwidth multiphase structure waveform synthesis method. The working principle of the system and realization method are described in detail,the simulation and analysis of this method is given. Sine wave and FM synthesized by this waveform synthesis method preform well in requency domain.
