Delayed logic signal.

/Physical Modeling/Electrical/Control/General Control/On-Off Delay

Description

The On-Off Delay block 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:

An on transition (change in the input signal from 0 to 1) is detected.
An off transition is detected (change in input signal from 1 to 0).
Any of the transitions is detected.

The operation of the on-off delay is shown in the figure.

Ports

Input

# u — input signal
scalar

Details

Input logic signal.

Data types	`Bool`.
Complex numbers support	No

Output

# y — output signal
scalar

Details

Delayed output signal.

Data types	`Bool`.
Complex numbers support	No

Parameters

Main group

# ON delay time, s — input delay time when switching on

Details

Specify the delay time when the input signal changes from 0 to 1.

Default value	`0.01`
Program usage name	`time_delay_on`
Evaluatable	Yes

# OFF delay time, s — input delay time when switching off

Details

Specify the delay time when the input signal changes from 1 to 0.

Default value	`0.0`
Program usage name	`time_delay_off`
Evaluatable	Yes

# Initial state — initial signal state

Details

Specify the initial state (0 or 1).

Default value	`0.0`
Program usage name	`initial_condition`
Evaluatable	Yes

# 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.

Default value	`0.001`
Program usage name	`sample_time`
Evaluatable	Yes
