摘要
介绍了一种在SDP平台下对多种交流信号采样时采用的一种异步采样方法,分析了由于异步采样所造成的相位系统误差,主要给出了相位和幅值校准的算法公式。最后利用Matlab进行了结果的仿真。
The article introduces （digital signal processor）platform sampling. The article chiefly gives Matlab toolbox,the result has been an asynchronous sampling method for muhicircuit ac signal based on DSP , and also analyzes the phase system error produced by the asynchronous the algorithm formulae for calibrating the amplitude and phase. By using simulated at last.
