Comparative Study on Decreasing Noise Between Wavelet Transform and Fourier Transform
Lin Chun-li · Journal of Lanzhou Polytechnic College · 2005
Because of its better time-frequency characteristic,wavelet transform can be used to decrease the noise in the signal effectively.Compared to the Fourier Transform,wavelet transform is superior and it is sensitive to the singularity signal,which enables it to reveal its great advantages in denosing unsteady signals.
