| Abstract: | Noise pollution is a problem for both input signal and output signal in mode test. In order to obtain useful signal, have to deal with the noise. In this paper, the results of reducing noise show that the different signal has different method . The results of the research indicate the method is an effective means to resolve the common problem. |
