Fixed-Point Blockset

Example: Converting from Doubles to Fixed-Point

The purpose of this example is to show you how to simulate a continuous real- world doubles signal using a generalized fixed-point data type. The model used is the simplest possible model and employs only two fixed-point blocks. Although simple in design, the model gives you the opportunity to explore many of the important features of the Fixed-Point Blockset including

• Data types
• Scaling
• Rounding
• Logging minimum and maximum simulation values to the workspace
• Overflow handling

The model used in this example is given by the fxpdemo_dbl2fix demo. You can launch this demo by typing its name at the MATLAB command line:

• fxpdemo_dbl2fix
  

The model is shown below.
