Multiplexer ndi chipangizo chamagetsi chomwe chimatha kusintha ma siginecha angapo kukhala magulu azizindikiro.

Zida za Multiplex nthawi zambiri zimagwiritsidwa ntchito popanga ma digito kapena ma Analogi kuti asankhe kapena kusinthana pakati pa ma siginali angapo.Ma multiplexers operekedwa ndi Qualwave akuphatikiza ma diplexers ndi ma triplexers.

Duplexer, yomwe imadziwikanso kuti antenna common, imakhala ndi ma seti awiri a Band-stop fyuluta yokhala ndi ma frequency osiyanasiyana.Pogwiritsa ntchito magawano afupipafupi a masitepe apamwamba, pass pass, kapena bandpass zosefera, mlongoti womwewo kapena chingwe chotumizira chitha kugwiritsidwa ntchito panjira ziwiri, potero kukwaniritsa ndi kutumiza ma siginecha awiri kapena kupitilira apo ndi mlongoti womwewo.

Triplex imakhala ndi zosefera zitatu (madoko) omwe amagawana node imodzi (doko).Kuyika kwa ma passband ndikuzipatula kwa duplexer ndizofanana ndi za duplexer.Mu ma frequency division duplex systems, kachitidwe kofala ka triplex ndikuphatikiza ma diplex awiri kukhala triplex imodzi.

Zofunika za multiplexer:

1. Zizindikiro zingapo zolowera zitha kuphatikizidwa kukhala chizindikiro chimodzi chotulutsa kuti mukwaniritse kutumizirana ma signal ophatikizika.
2. Njira zolowera zosiyana zitha kusankhidwa kuti zikwaniritse kufalikira kwa ma sign angapo nthawi imodzi.
3. Kawirikawiri, zipata zomveka (monga NDI zipata, OR zipata, etc.) ndi zosintha (monga zipata zotumizira, zosankha, ndi zina zotero) zimagwiritsidwa ntchito popanga ma multiplexers.

Kugwiritsa ntchito multiplexer:

1. Njira yolumikizirana: Imagwiritsidwa ntchito kwambiri pamakina olankhulirana, ntchito imodzi yodziwika bwino ndikuphatikiza ma siginecha angapo olumikizirana kuti akhale chizindikiro chimodzi cholumikizirana bwino.
2. Digital circuit design: Ikhoza kugwiritsidwa ntchito pokonza ndi kutumiza zizindikiro zambiri pamapangidwe a digito.
3. Kusungirako deta: Ikhoza kugwiritsidwa ntchito kusungirako deta kuti ikwaniritse zolowetsa panthawi imodzi ndi kutulutsa zizindikiro zambiri mwa kusankha njira zolowera zosiyana.
4. Kusintha kwaukadaulo: Ndilo gawo lofunikira muukadaulo wosinthira womwe umagwiritsidwa ntchito posankha njira zosiyanasiyana zolowera ndi zotulutsa kuti mukwaniritse kusintha kwamakanema ambiri.

Qualwaveimapereka kukana kwakukulu koyimitsa kakulidwe kakang'ono kochulukitsa ma frequency osiyanasiyana DC-14GHz.Ma multiplexers amagwiritsidwa ntchito kwambiri pazinthu zambiri.
