摘要
针对基于DDS技术的三相六通道信号源设计,给出了系统的硬件设计及软件设计方法。该系统以DSP芯片TMS320C6713为核心,可产生六路高精度低频三相正弦信号,每路的频率、相位和幅度均可调节,且能够叠加2~21次谐波。
Aim at the design of six lines triphase signal source based on DDS technology, the design methods of hardware and software were given out. Taking TMS320C6713 as core of the system, six lines high accuracy low frequency triphase sine signal can be generated, the frequency, the phase and the amplitude of each signal can be adjusted, 2~21 harmonic can be overlapped.
