Appendix 1 How to Calculate the Area of a Waveform

Integ1TY

Sum of only the positive curve areas : S

+ S

Integ2TY

Sum of the positive and negative curve areas: S

+ S

– S

Integ1XY

(1) Multiple Loops

Start point,

stop point

Area S = n × S

n: The number of loops

(2) Non-Closed Curve

Start point

Stop point

(3) Loop Tracing a Figure-Eight

Area S = |S

– S

(4) Loop Tracing a Spiral

Stop point

Start point

Stop point

Start point

Waveform

Area S = S

Area enclosed by a curve

connecting the start and stop points

Area S = S

× 2 + S

The number of overlaps varies

according to the number of loops.
