<p>From calculations with the three input signals, it is found that 12 interfering frequencies are produced, three of which lie on one of the original incoming frequencies. Note that these three frequencies which lie at the original incoming frequencies are typically attributed to <a href="page.php?w=self-phase_modulation">self-phase modulation</a></p><p>
