Description

This block converts an IQ number in a particular Q format to a different Q format.

Note

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.

Parameters

Q value

Q value from 1 to 30 that specifies the precision of the output
