_IQNmpyIQX.c File Reference

Detailed Description

Functions to multiply two IQ numbers in different IQ formats, returning the product in a third IQ format. The result is neither rounded nor saturated, so if the product is greater than the minimum or maximum values for the given output IQ format, the return value will wrap around and produce inaccurate results.
