demultiplexer
Meaning: A device that takes a single input signal and routes it to one of several output channels, performing the reverse function of a multiplexer. Commonly abbreviated as DEMUX.
Demultiplexers are paired with multiplexers in communication systems to separate combined signals back into their individual components at the receiving end. In digital electronics, a demultiplexer uses select lines to direct data from one input to the chosen output line. The term is highly specialised and confined almost entirely to electronics engineering, telecommunications, and computer science literature.
Examples
- The demultiplexer at the receiving station separated the combined signal back into its sixteen original wavelength channels. 接收站的解复用器将合并信号分离回原来的16个波长通道。El demultiplexor de la estación receptora separó la señal combinada en sus dieciséis canales de longitud de onda originales.受信局のデマルチプレクサは、統合信号を元の16の波長チャネルに分離した。수신국의 디멀티플렉서는 결합된 신호를 원래의 16개 파장 채널로 분리했다.
- A one-to-eight demultiplexer distributed the serial data stream to the appropriate memory bank based on the address decoder output. 一对八解复用器根据地址解码器的输出,将串行数据流分配到适当的存储体。Un demultiplexor de uno a ocho distribuyó el flujo de datos en serie al banco de memoria apropiado en función de la salida del decodificador de direcciones.1対8デマルチプレクサが、アドレスデコーダの出力に基づいてシリアルデータストリームを適切なメモリバンクに分配した。1대8 디멀티플렉서가 주소 디코더의 출력에 기반하여 직렬 데이터 스트림을 적절한 메모리 뱅크에 분배했다.
- The fibre-optic demultiplexer proved essential for routing individual subscriber signals from the shared backbone connection. 光纤解复用器在从共享骨干连接中路由各用户信号方面发挥了至关重要的作用。El demultiplexor de fibra óptica resultó esencial para encaminar las señales de cada abonado desde la conexión troncal compartida.光ファイバーデマルチプレクサは、共有バックボーン接続から個々の加入者信号を振り分ける上で不可欠であった。광섬유 디멀티플렉서는 공유 백본 연결에서 개별 가입자 신호를 분배하는 데 필수적이었다.
