Abstract
The paper deals with the influence of mains interference on time coherent averaging using an internal trigger. The general distribution of the time jitter is derived and applied to a simplified signal. The authors prove that no amount of averaging can do away with this type of interference. Finally, the deformation this type of jitter has on a step signal is computed.
摘要
本文探讨了市电干扰对使用内部触发器进行时间相干平均的影响。推导了时间抖动的一般分布，并将其应用于一个简化信号。作者证明，无论进行多少次平均都无法消除这种干扰。最后，计算了这种抖动对阶跃信号的畸变。
