直流信号
direct current signal
- 如果输入端的交流电压很大，其一部分信号被整流，于是在被测的直流信号中产生了误差。
If the AC voltage at the input is large, part of this signal is rectified, producing an error in the DC signal being measured. - 本文提出一种放大微弱直流信号的方法，同时设计了实现这一方法的直流放大器电路。
In this paper, a method used to amplify faint direct current signal is put forward, and the circuits of direct current amplifier to realize the method are devised. - 同直流信号直接耦合处理相比，交流信号耦合虽然要增设调制解调装置，但对后级信号处理电路的器件要求更低，信噪比更高。
Compared with DC coupling signal processing, it need lower requirement of signal processing circuit and have the merit of high signal-to-noise performance although it require the device of modem.
