Editing Overlap zone

{{Short description|Zone where radio signals of the same frequency can be received}}

In [[radio frequency engineering]], an '''overlap zone''' occurs where signals from two or more [[radio station]]s, transmitting at the same frequency, can be received with comparable intensity.<ref>{{cite web | url=https://www.semanticscholar.org/topic/Overlap-zone/1341301 | title=Overlap zone &#124; Semantic Scholar }}</ref> [[Co-channel interference|Interference]] occurs frequently in such a zone.<ref>{{Cite web |url=https://www.semanticscholar.org/topic/Overlap-zone/1341301 | title=Overlap zone |access-date=2023-04-02 |website=www.semanticscholar.org}}</ref>

In order to avoid this, a receiver with [[directional antenna]] is used, which can then be aligned in such a way that it will only receive the signal of one transmitter. Alternatively, the signals could be separated using a demodulator in [[single sideband|single sideband mode]].{{citation needed|date=December 2022}}

With [[digital radio]] ([[Digital Radio Mondiale]] and [[Digital Audio Broadcasting]] being two common types), there is no interference in the overlap zone.<ref>{{Cite web |title=Why don't radio stations interfere with each others broadcasts? |url=https://www.physicsforums.com/threads/why-dont-radio-stations-interfere-with-each-others-broadcasts.307249/ |access-date=2023-04-02 |website=Physics Forums {{!}} Science Articles, Homework Help, Discussion |date=14 April 2009 |language=en-US}}</ref>
