VariableTransportDelay

VariableTransportDelay is an operator simulating a variable time delay.

upper input: in
lower input: Tt

Element	Direction	Remark
in::continuous	input	operator input
Tt::continuous	input	variable time delay
out::continuous	output	operator output
internal1::sdisc[5]		discrete state; reserved for internal calculations internal1[0] is the counter controlling the initial cycle internal1[1] is the number of delay steps internal1[2] is the input pointer for the stack internal1[3] is the output pointer for the stack internal1[4] is the available length of the stack
internal2::continuous[1]		discrete state; reserved for internal calculations internal2[0] is the previous integration step size
stack::continuous[internal1[4]]		discrete state; stack Adjust the length of stack in the element's properties editor.
helpstack::continuous[internal1[4]]		steplocal variable; stores values in case of interactive modification of h Adjust its length to that of stack.

The least permitted value for the number of delay steps is 1.

Delay steps are counted in integration steps sizes h.

Interactive modifications of the integration step size h are treated explicitly, thus the output always shows smooth behaviour. Simultaneous modifications of h and Tt are possible.
