微信号检测中最难避免的就是干扰问题,特别是在信号仅为微伏级时,信号相对于干扰来说,几乎被完全淹没,因此,研究如何在干扰信号很大的情况下尽可能地检测出有用信号有着极其重要的意义。X9313是Xicor公司推出的一种数字电位器,在某微弱信号检测装置中,采用X9313可成功解决干扰信号过大的问题。
- Abstract:
- Interference is most difficult to be avoided while measuring the weak signal, Especially when the signal is only at microvolt level.X9313 is a kind of digitally controlled dissurbacne potentiometer produced by Xicor company.We succeed in using it to solve the problem that the signal is too strong, and get the useful signal in a weak signal measurement device.
