基于FPGA数字信号发生器的设计

The Design of Digital Signal Generator Based on FPGA

在生产实践和科技领域中,信号发生器有着广泛的应用,可以产生三角波、锯齿波、矩形波、正弦波等波形。基于此,提出了一种基于Xilinx FPGA IP CORE设计方法,调用已封装好的DDS core、Comparators core、ROM core产生所需的波形,实现预定指标的多波形输出。

In the field of production practice and science and technology, different frequency signal generators are widely used, such as triangle wave, sawtooth wave, square-wave and sine wave. A new design method based on Xilinx IP CORE is introduced in this paper, it directly applies the waveform operated by the encapsulated DDS core, Comparators core and ROM core to achieve the multi- wave output of predetemained target.
