Description
Block On-Off Delay applies a delay to the input logic signal.
A time delay is added when a transition is detected in the input signal. This block allows you to add a time delay to the input signal when:
-
A switch-on transition has been detected (a change in the input signal from
0on1). -
A switch-off transition has been detected (a change in the input signal from
1on0). -
Any of the transitions is detected.
The operation of the on/off delay is shown in the figure.
Parameters
Main group
# ON delay time, s — input delay time when switching on

# Sample time — interval between calculation steps
Details
The time between successive executions of the block. During execution, the block produces output data and updates its internal state if necessary.
For discrete time operation, set the parameters Sample time to a positive value. For continuous time operation, set the parameters Sample time to 0.
