Complex Phase Difference - Output phase difference between two complex input signals

Library

Utility Blocks

Description

The Complex Phase Difference block accepts two complex input signals that have the same size and frame status. The output is the phase difference from the second to the first, measured in radians. The elements of the output are between -π and π.

The input signals can have any size or frame status. This block processes each pair of elements independently.
