Abstract
The aim of this paper is to determine the instantaneous components of a high-speed spinning moving body by means of the pseudo discrete Wign er-Ville distribution (PDWVD). The data access generates an enslaved s ampling and, due to the friction forces, the sampling is non-uniform. With respect to sufficient sampling conditions, the PDWVD may be appli ed in a straight form to the non-uniformily distributed samples. Simul ated and real signals are analysed.
