Delay signal one sample period, with external Boolean reset and initial condition
Additional Math & Discrete / Additional Discrete
The Unit Delay Resettable External IC block delays a signal one sample period.
The block can reset its state based on an external reset signal
The block has two input ports, one for the input signal
the other for the reset signal
R. When the reset
signal is false, the block outputs the input signal delayed by one
time step. When the reset signal is true, the block resets the current
state to the initial condition given by the signal
outputs that state delayed by one time step.
You specify the time between samples with the Sample
time parameter. A setting of
that the block inherits the Sample time.
The Unit Delay Resettable External IC block accepts signals of the following data types:
The data types of the inputs
be the same. The output has the same data type as

Specify the time interval between samples. To inherit the sample
time, set this parameter to
