In summary, the gate checks that the following conditions are met:		An [[Glossary of Terms#R\|RTG Gate]] runs an algorithm to determine if a Phase Inversion occurs. In summary, the gate checks that the following conditions are met:
	* Absolute Peak Amplitude exceeds the Consider Threshold		* Absolute Peak Amplitude exceeds the Consider Threshold
	* No Negative Peak is found or a negative peak occurs '''after''' the Positive Peak		* No Negative Peak is found or a negative peak occurs '''after''' the Positive Peak
