Fourier Series Analysis for Novel Spatiotemporal Pulse Waves: Normal, Taut, and Slippery Pulse Images
Table 2
Fourier series analysis of normal, taut, and slippery pulses.
| Pulse type | Fourier series analysis of spatiotemporal pulse waves | Temporal analysis | Spatial analysis | Spatial harmonic ratio sequence |
| Normal pulse | Undistinguishable | Base and first harmonic share importance | Three sequences are well distributed | Taut pulse | Behaves as a rectangular pulse with dominant base and little harmonics | Base is high, and others merged together | Slippery pulse | The first harmonic can be higher or lower than the second one | Three sequences intersect each other |
