基于DDS与FPGA的信号产生器设计与实现

DESIGN AND IMPLEMENTATION OF THE SIGNAL GENERATOR BASED ON DDS AND EPGA

采用四通道DDS芯片及FPGA器件,设计了多种参数均可自由设置的双通道信号产生器。阐述了信号产生器的主要组成及工作原理,给出了FPGA实现后的VHDL原理框图及具体应用实例,解决了现有设备检修检测手段不足的问题。

By adopting DDS chips and FPGA devices, design a kind of flexible multi-parameter dual-channel signal generator, expatiate its main components and working principles, present the VHDL working prineipium, as well as its specific application instances after the realization of FPGA, and solve the insufficience of the existing equipment overhaul measures.
