A reading offset may be caused by inputamplifier 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。
2
Each channel has a channel signal switch, high-performance microphone inputamplifier circuit.
各通道设有通道信号切换开关，话筒输入设置高性能放大电路。
3
The amplifierinput is a voltage proportional to the photocurrent signal produced by a photodiode, which is irradiated by a modulated light beam at the same chopper frequency.
