针对陷波器不能有效滤除工频及各高次谐波的情况,提出了一种在低频微弱信号检测中消除工频干扰的零点采样新方法,该方法通过跟踪工频信号产生间隔与工频周期相同的脉冲序列,对混合信号进行过零同步采样。
补充资料：采样点
(samplingsite)根据不同污水来源而决定的采取水样的地点。供水系统有三种采样点：(1)凈化处理前采取原生水水源；(2)凈化处理后采取供水水源；(3)在配水系统内采取出水口水源。工业污染源有两种采样点：(1)从最后排泄到河流中，从城市的集中系统中和污水管适中采取原状污水水源；(2)对被限制的特殊工业污染源应沿排放口向源逆行采取附加水样。污水处理场有两种采样点：(1)在未处理的废水注入点采样；(2)在处理后的出流点采样。地面河流有两种采样点：(1)在交流汇入口、工业污染源的污水出口和污水处理场的出口等的上游和下游两个地点采样；(2)为满足分析要求而专门采样。
