Engineering:Overlap zone
In radio frequency engineering, an overlap zone occurs where signals from two or more radio stations, transmitting at the same frequency, can be received with comparable intensity.[1] Interference occurs frequently in such a zone.[2]
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 mode.[citation needed]
With digital radio (Digital Radio Mondiale and Digital Audio Broadcasting being two common types), there is no interference in the overlap zone.[3]
