Description

The Difference block outputs the current input value minus the previous input value.

Parameters and Dialog Box

Initial condition for previous output

Set the initial condition for the previous output.

Output data type and scaling

Specify the output data type and scaling via the dialog box, or inherit the data type and scaling from the driving block or by backpropagation.

Round toward

Rounding mode for the fixed-point output.

Saturate to max or min when overflows occur

If selected, fixed-point overflows saturate.
