Abstract

In this paper, we will pay attention to the spline wavelets which are real-type wavelets and have good characteristics such as compact support, the symmetric property and so on. We propose an RI-Spline wavelet which is complex-type wavelet and has the compact support, and we confirm the effectivity of this wavelet in the continuous case by a model signal. Next, for the application of the spline wavelets to control golf sound, we examine the relation between golf impact sound and vibration velocity of golf club. As a result, it is found that using the continuous and discrete wavelet transform together is effective for the analysis of the sound and the vibration. This technique will be useful for the unsteady signal analysis
