Abstract
Femoral rotational waveforms sampled at 15 Hz for a duration 20 s satisfy the sampling rate and frequency resolution requirements of such waveforms during walking. Spectral analysis provides a unique signature of the frequency composition of such signals. This identity may prove useful in characterising human gait and could be of value in future studies of walking in health and disease.
摘要
以15赫兹的频率采样20秒的股骨旋转波形满足了行走过程中此类波形的采样率和频率分辨率要求。频谱分析提供了此类信号频率组成的独特特征。这种特征可能在表征人类步态方面有用，并且在未来关于健康和疾病状态下行走的研究中可能具有价值。
