C2000 Saturate IQN

Saturate IQ number


This block saturates an input IQ number to the specified upper and lower limits. The returned value is an IQ number of the same Q value as the input.


The implementation of this block does not call the corresponding Texas Instruments® library function during code generation. The TI function uses a global Q setting and the MathWorks® code used by this block dynamically adjusts the Q format based on the block input. See Using the IQmath Library for more information.
