Asynchronous Sample & Hold
The value of the output signal at time zero. The output of the block remains at this
value until the block is triggered by a rising trigger signal becoming positive. The
default value is 0.
Ports
The block has two physical signal input ports and one physical signal output port.
Examples
The Asynchronous PWM Voltage Source example illustrates how you can use the
Asynchronous Sample & Hold block to build components with more complex behaviors.
For an alternative discrete-time implementation, see the Discrete-Time PWM Voltage
Source example. The discrete-time version is better suited to fixed-step solvers and
hardware-in-the-loop applications, whereas the asynchronous implementation is better
suited to fast desktop simulation using variable-step solvers.
