A reading offset may be caused by input amplifier overload or DC rectification at the input.
读数偏置可能由输入放大器过载或输入端的直流整流效应所引起。
A new type of DC current comparator is researched which includes two parts: a bidirectional self saturating magnetic amplifier and a two care self saturating magnetic amplifier.
研究了一种新型直流电流比较仪，它包括两个环节：双向自饱和磁放大器和双铁芯自饱和磁放大器。
Based on a direct-conversion architecture, the receiver integrates LNA, I/Q mixer, DC-offset removal filter, baseband amplifier and channel-select filters on a single chip.
基于直接下变频的系统架构，接收机集成了低噪声放大器、I/Q下变频器、去直流偏移滤波器、基带放大器和信道选择滤波器。
About the power supply, the filaments can be powered by AC or DC except that the 3a5 (version 2 of the amplifier) requires a DC filament supply.
就电源而言，灯丝用交、直流供电均可，但是版本二中的3a5除外，它必须用直流供电。
