As for the limitation of traditional frequency, the concept of local frequency is proposed, which makes the physical meaning of frequency more clear. The wide adaptability of local frequency is also discussed. Moreover, a novel time-frequency analysis approach is presented based on local frequency and EMD. The time-frequency distributions of simulated signals are investigated by the new approach....
