This paper proposes a Lissajous's diagram visualization method based on a multi-resolution analysis of the discrete wavelets. We apply our approach to a signal processing of a differential type magnetic position sensor for the metallic objects. We apply a wavelet transform to the sensor output signals in order to work out a Lissajous's diagram. As a result, we have succeeded in extracting the distinct signal characteristics. Thus, it is revealed that our Lissajous's diagram methodology based on the wavelets transform may become one of the distinguished methodologies for a signal processing technique.
