Analysis on the Test Performance of the Correlator
Xi Yang · Journal of Xinxiang University · 2009
Correlator is the key element of lock-in amplifier which belongs to weaker signal test instruments.Lock-in amplifier is good at restrainning noise,mainliy because of its excellent performance of eliminating noise and interference.This paper tests and analyses the performance of the correlator via experiments,it shows that the correlator can restrain noise stongly,it can detect weaker signal effectively which is submerged in the noise.
