This paper proposes a vectorized signal 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. At first, to derive a frequency domain information, we apply a conventional FFT analysis to the sensor output signals. Second, we apply a wavelet transform to the sensor output signals. After expanding the sensor output signals into a multi-resolution form, we comprise a series of the signal vectors by combining the low level on and off loaded signals. As a result, we have succeeded in visualizing the no-load and target reaction output signals. Thus, it is revealed that our vectorization methodology based on the wavelet analysis may becomes one of the distinguished methodologies for a signal processing technique.
