Interval Test

Determine if signal is in specified interval

Library

Logic and Bit Operations

Description

The Interval Test block outputs TRUE if the input is between the values specified by the Lower limit and Upper limit parameters. The block outputs FALSE if the input is outside those values. The output of the block when the input is equal to the Lower limit or the Upper limit is determined by whether the boxes next to Interval closed on left and Interval closed on right are selected in the dialog box.

Data Type Support

The Interval Test block accepts signals of the following data types:

  • Floating point

  • Built-in integer

  • Fixed point

  • Boolean

  • Enumerated

    In this case, the Upper limit and Lower limit values must be of the same enumerated type.

For more information, see Data Types Supported by Simulink in the Simulink® documentation.

Parameters and Dialog Box

Interval closed on right

When you select this check box, the Upper limit is included in the interval for which the block outputs TRUE.

Interval closed on left

When you select this check box, the Lower limit is included in the interval for which the block outputs TRUE.

Lower limit

The lower limit of the interval for which the block outputs TRUE.

Output data type

Select the output data type: boolean or uint8.
