# 12.3.4 Overloading results

As a result of the equation described in Annex A5.4, for each event and at each frequency, the sum of the iRSS<sub data-renderer-mark="true">overloading</sub> (iRSS<sub data-renderer-mark="true">sum\_overloading</sub>) will be compared to the overloading treshold O<sup data-renderer-mark="true">th</sup>(f<sub data-renderer-mark="true">i</sub>) at that frequency (f<sub data-renderer-mark="true">i</sub>). The difference, delta (in dB), will be stored.

- When delta ≥ 0, then the receiver is overloaded at that f<sub data-renderer-mark="true">i</sub> (i.e. the rest of the frequency do not matter);
- When delta &lt; 0, then the receiver is not overloaded at f<sub data-renderer-mark="true">i.</sub>

If only one frequency is present, the iRSS<sub data-renderer-mark="true">sum\_overloading</sub> is compared to the O<sup data-renderer-mark="true">th</sup>(f<sub data-renderer-mark="true">i</sub>)and the difference will be stored for that event. If more than one frequency is present, the highest delta value will be indicated in the vector (i.e. irrespective of the frequency) such that

for each event j (where dRSS &gt; sensitivity){

for Frequency = i to number of total frequencies{ delta\_max(j) = max(delta(f<sub data-renderer-mark="true">i</sub>)); } (Eq. 67)
