The pattern tri period is the same definition in pattern type as the
$pattern_tri_period pattern_tri_num pattern_type int_period_num f_period_spacing
if_empty
Parameter Explanation
- pattern_tri_num : number of empty section.
- type : type1=triangle, type2=circle, type3=ellipse, type4=rectangular, type5=Sinkx function up, type6=Sinkx function down, type7=Sinkx function up, type8=Sinkx function down.
- f1-f6 : you can refer to the information where at bottom of this page.
- int_period_num :
- f_period_spacing :
Example
Type.1~4 are triangle, circle, ellipse and rectangle.
If the parameters are not show in the figure, you should set those parameters as 0.
Type5~8 are sine shape period structure.
Type.5 and 6 can be determined by this expression:
Type.7 and 8 can be determined by this expression:
