Returns a 3rd order exponential delay of the input, conserving the input if the delay time changes. Equivalent to the equations:
DELAY3=LV3/DL
LV3=INTEG(RT2-DELAY3,DL*input)
RT2=LV2/DL
LV2=INTEG(RT1-RT2,LV3)
RT1=LV1/DL
LV1=INTEG(input-RT1,LV3)
DL=delay time/3
DELAY3I=LV3/DL
LV3=INTEG(RT2-DELAY3I,
initial value*DL)
RT2=LV2/DL
LV2=INTEG(RT1-RT2,LV3)
RT1=LV1/DL
LV1=INTEG(input-RT1,LV3)
DL=delay time/3

| Units: | DELAY3(units,time) --> units DELAY3I(units,time,units) --> units |
The input units match the output units. The units of delay time must match those of TIME STEP. For DELAY3I units for the initial value must match those of the input.
Example
S = STEP(10,40)
delay time = 20
init output = 5
DS = DELAY3(S,delay time)
DSI = DELAY3I(S,delay time,init output)
