_IQNrsmpy.c File Reference

Detailed Description

Functions to multiply two IQ numbers, returning the product in IQ format. The result is rounded and saturated, so if the product is greater than the minimum or maximum values for the given IQ format, the return value is saturated to the minimum or maximum value for the given IQ format (as appropriate).
