About: Overlap zone

An Entity of Type: settlement, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

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. Interference occurs frequently in such a zone. 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.

dbo:abstract
  • 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. Interference occurs frequently in such a zone. 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. With digital radio (Digital Radio Mondiale and Digital Audio Broadcasting being two common types), there is no interference in the overlap zone. (en)
  • 重疊區是中的詞，是在在二個或多個之間的區域，在此區中各廣播站以相同的頻率發射訊號，而且接受到的強度相當。在此區域中會出現的情形。 為了避免此一情形，會使用有的接收器，天線方向調整到只接收到一個廣播站的訊號。或者可以用单边带调制的方式來调制訊號。 若是數位廣播（包括DRM及DAB），则沒有重疊區的干擾問題。 (zh)
