摘要
An improved exponential time-frequency distribution is presented. Compared with those exponential time-frequency distributions represented by the Choi-Williams distribution, this distribution is designed to suit the properties of mechanical vibration signals, and is easier to be applied in the mechanical vibration signal processing. It has a strong cross-term suppression ability and is aliasing free.
