Delay a signal one sample period, if the external enable signal is on, with an external initial condition
Library
Additional Math & Discrete / Additional Discrete
Description
The Unit Delay Enabled External IC block delays a signal by one sample period when the enable signal E is on. While the enable is off, the block holds the current state at the same value and outputs that value. The enable E is on when E is not 0, and off when E is 0.
The initial condition of this block is given by the signal IC.
The input u and IC data types must be the same, and are any data type. The output data type is the same as u and IC. The enable E is any data type.
You specify the time between samples with the Sample time parameter. A setting of -1 means the Sample time is inherited.
Data Type Support
The Unit Delay Enabled External IC block accepts signals of any data type supported by Simulink, including fixed-point data types.
Parameters and Dialog Box
-1. See Specifying Sample Time in the online documentation for more information.
