| 摘 要： | 针对采样频率选取不当使采集的电火工品发火信号波形失真问题，研究了在实际采样过程中采样频率的取值方法。首先根据发火信号的特征，设计了采样方案；然后利用虚拟仪器软件对发火信号进行频谱分析，确定合适的采样频率和采样点数，进而采集完整的信号波形；最后结合试验数据对采样频率的选取进行了分析，得出了在实际采样过程中采样频率的取值规律。

| Abstract: | Aiming at the problem of waveform distortion caused by chosing unsuitable sampling rates when sampling firing signal of EED,a method of choosing sampling rates in actual application was studied. Firstly, according to the signal characteristic, a solution was designed for sam- pling waveform. Then spectrum analysis about firing signal was made using virtual instrument software,and ideal sampling rate and sampling points were determined to sampling waveform. Finally,with analysis of experiment data,the law of choosing sampling rates in actual application was obtained. |
