摘要
作为调频激励器的核心,提出了全数字调频激励器频率控制字的设计方法和理念,详细阐述了QUARTUSⅡ联合MATLAB的软件设计,论证了DDS与DSP Builder设计双通道正弦信号源的可行性,完成了在ALTERA公司推出的FPGA平台上的软硬件设计。与其他方式来产生频率控制字,QUARTUSⅡ与MATLAB联合实现易于排错,并且降低了硬件电路调试的难度。
As the core of FM exciter, this paper presents the design idea and method of digital FM exciter frequency control word, describes in detail the software design of QUARTUS combined MATLAB, demonstrates the feasibility of DDS and DSP Builder generating double channel sine signal source, completes the hardware and software design with ALTERA＇s FPGA platform. Compare with other ways to generate the frequency control word, QUARTUS Ⅱ with MATLAB joint realization is easy to debug, and re-duces the hardware circuit debugging difficulty.
