In this paper, impedance matching between LPF and surveying instrument is discussed and the design method is presented.
本文将对滤波器与测量仪器之间的阻抗匹配问题加以讨论,提出匹配衰减器的设计方法。
SDH, LDH, LPF were detected by the immunohistochemical method, and the histological changes were synchronously observed by electronic microscope.
免疫组化方法观察各组大鼠脑组织sdh、LDH、LPF的变化,同步观察电子显微镜下组织学变化。
This paper improved the harmonic current detection method based on UPF (unity power factor), using the slipped window integral to replace the LPF (low pass filter).
本文对基于单位功率因数的谐波电流检测方法进行了改进,用移动窗积分法取代检测中常用的低通滤波器。
LPF operates when a logout request comes from a client.
当客户机发来注销请求时,将使用LPF进行处理。
As the result of go though this process, I also simulate the LPF feature of amplitude-frequency by computer, and make analysis each step in the over-all scheme.
