Step 3:
Decide the execution time of every section and obtain the frequency of every section by table 5
Assume every section executes for 500ms, the equation for frequency (Hz) of each section is:
fx
1
= 1ч0.5 Ч
x1、fx
2
=1ч0.5 Ч x

Step 4:
Fill Device D into table 2 and complete all steps.
Reminder 1: When Rx=Ry, you can calculate X axis, and copy X axis to Y axis (as fy1 = fx10, fy2 =
fx9, …fy10 = fx1,and y1 = x10, y2 = x9,…y10 = x1 )
Reminder 2: When drawing a counterclockwise arc, switch the index value of X axis with that of Y axis.
