Fourier series analysis of normal, taut, and slippery pulses.

Pulse typeFourier series analysis of spatiotemporal pulse waves
Temporal analysisSpatial analysisSpatial harmonic ratio sequence

Normal pulseUndistinguishableBase and first harmonic share importanceThree sequences are well distributed
Taut pulseBehaves as a rectangular pulse with dominant base and little harmonicsBase is high, and others merged together
Slippery pulseThe first harmonic can be higher or lower than the second oneThree sequences intersect each other
