Unit Delay Enabled - Delay signal one sample period, if external enable signal is on

Library

Additional Math & Discrete / Additional Discrete

Description

The Unit Delay Enabled block delays a signal by one sample period when the external enable signal E is on. While the enable is off, the block is disabled. It holds the current state at the same value and outputs that value. The enable signal is on when E is not 0, and off when E is 0.

You specify the block output for the first sampling period with the value of the Initial condition parameter.

The output data type is the same as the input u data type. The data type of the input u and the enable E can be any data type.

You input the sample time with the Sample time parameter. A setting of -1 means the Sample time is inherited.

Data Type Support

The Unit Delay Enabled block accepts signals of any data type supported by Simulink software, including fixed-point and enumerated data types.

Parameters and Dialog Box

Initial condition

Initial condition.

Sample time

Specify the time interval between samples. To inherit the sample time, set this parameter to -1. See Specifying Sample Time in the online documentation for more information.
