Spectrum Feature of Step Signal with White Noise and Method of Noise Reducing

LI Yun-hua(Nantong Institute of Technology,Nantong226007,China)  
According to the spectrum feature of step signal with white noise,a method of noise reducing by using discrete wavelet transtormation is introduced in this paper.The simulation shows that,if we choose proper threshold,the effect of noise reducing by using discrete wavelet is better than that of noise reducing by using ideal lowpass-filter based on DFT.
