摘要
By applying Wigner distribution, which has high time resolution and high random noise reducing capability, to the acoustic bio-signals, the possibility of early diagnosis in both intracranial vascular deformation and prosthetic cardiac valve malfunction increased. Especially in latter case, 1st-order local moment of the distribution showed its effectiveness.
