Abstract
A system and method include measuring differences in delay and phase offset between signals transmitted through different channels within a single common bandwidth, comprising steps of transmitting an identical signal through both separate channels at a same frequency; combining signals from two separate channels so that they constructively and destructively interfere at different frequencies; analyzing amplitude versus frequency characteristic of the combined signal such that when the signals are not matched in phase, delay and amplitude, a change in amplitude is determined across the common bandwidth as the combined signals constructively and destructively interfere at different frequencies; analyzing frequency content of the changing amplitude that represents rate of constructive and destructive interference; determining change in rate of constructive and destructive interference as amplitude changes between constructive interference and destructive interference; and identifying tones that have a best constructive and destructive interference representing a null outside the source or common bandwidth.
