FixPt Zero-Order Hold
Implement a zero-order hold of one sample period.
Description
The FixPt Zero-Order Hold block is a masked S-function that samples and holds its input for the specified sample period.
The block accepts one input and generates one output, both of which can be scalar or vector. If the input is a vector, all elements of the vector are held for the same sample period.
The block provides a mechanism for discretizing one or more signals in time, or resampling the signal at a different rate. If your model contains multirate transitions, you must add FixPt Zero-Order Hold blocks between the fast to slow transitions where the sample rate must be set to that of the slower block. For slow to fast transitions, use the FixPt Unit Delay block.
Dialog Box Parameters
- Sample time - The time between samples.
