First-Order Hold

Implement first-order sample-and-hold

  • Library:
  • Simulink / Discrete

Description

The First-Order Hold block implements a first-order sample-and-hold that operates at the specified sampling interval. This block has little value in practical applications and is included primarily for academic purposes.

This figure compares the output from a Sine Wave block and a First-Order Hold block.
