Output the signal and the signal delayed by one sample period, if the external enable signal is on, with an external Boolean reset
Library
Description
The Unit Delay With Preview Enabled Resettable block supports calculations that have feedback and depend on the current input.
The block can reset its state based on an external reset signal R. The block has two output ports. When the external enable signal E is on and the reset R is false, the upper port outputs the signal and the lower port outputs the signal delayed by one sample period. The block has two input ports, one for the input signal u and the other for the enable signal E.
When the enable signal E is on and the reset R is true, the block resets the current state to the initial condition given by the Initial condition parameter. The block outputs that state delayed by one sample time through the lower output port, and outputs the state without a delay through the upper output port.
When the Enable signal is off, the block is disabled, and the state and output values do not change, except for resets. The enable signal is on when E is not 0, and off when E is 0.
The input u and initial condition IC must be the same data type, but can be any data type. The output is the same data type as the inputs u and IC. The reset R can be any data type.
You specify the time between samples with the Sample time parameter. A setting of -1 means the Sample time is inherited.
