Delay a signal one sample period, if the external enable signal is on
Library
Description
The Unit Delay Enabled block is a masked block that 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 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.
