Multiplexer ke sesebelisoa sa elektroniki se ka fetolang likanale tse ngata tsa matšoao hore e be sete ea liteishene tsa matšoao.

Lisebelisoa tsa Multiplex hangata li sebelisoa ts'ebetsong ea mats'oao a dijithale kapa Analog ho khetha kapa ho chencha har'a matšoao a mangata a kenyellelitsoeng.Li-multiplex tse fanoeng ke Qualwave li kenyelletsa diplexers le triplexers.

Duplexer, eo hape e tsejoang e le antenna common, e na le lihlopha tse peli tsa Band-stop filthara e nang le maqhubu a fapaneng.Ka ho sebelisa ts'ebetso ea karohano ea maqhubu a "high pass", "low pass" kapa lifilthara tsa "bandpass", "antenna" e tšoanang kapa mohala oa phetisetso o ka sebelisoa bakeng sa litsela tse peli tsa mats'oao, ka hona, ho amoheloa le ho fetisoa ha matšoao a mabeli kapa ho feta a fapaneng ka antenna e le 'ngoe.

Triplex e na le li-filters tse tharo (likou) tse arolelanang node e le 'ngoe (port).Lipheo tsa ho kenya li-passband le ho itšehla thajana tsa duplexer li tšoana le tsa duplexer.Litsamaisong tsa "frequency division duplex", ts'ebeliso e tloaelehileng ea triplex ke ho kopanya li-diplex tse peli ho etsa triplex e le 'ngoe.

Likarolo tsa multiplexer:

1. Lipontšo tse ngata tsa ho kenya li ka kopanngoa hore e be pontšo e le 'ngoe ea tlhahiso ho finyella phetisetso e kopanetsoeng ea matšoao.
2. Litsela tse fapaneng tsa ho kenya li ka khethoa ho finyella phetiso ea nako e le 'ngoe ea lipontšo tse ngata.
3. Hangata, liheke tsa logic (tse kang AND liheke, OR liheke, joalo-joalo) le li-switches (tse kang liheke tsa phetisetso, likhetho, joalo-joalo) li sebelisetsoa ho haha li-multiplexers.

Tšebeliso ea multiplexer:

1. Sistimi ea puisano: E sebelisoa haholo lits'ebetsong tsa puisano, ts'ebeliso e le 'ngoe e tloaelehileng ke ho kopanya matšoao a mangata a puisano hore e be lets'oao le le leng bakeng sa phetiso e nepahetseng ea puisano.
2. Moralo oa potoloho ea dijithale: E ka sebelisoa ho sebetsa le ho fetisa matšoao a mangata ka moralo oa potoloho ea dijithale.
3. Ho boloka boitsebiso: E ka sebelisoa bakeng sa polokelo ea data ho finyella ho kenya letsoho ka nako e le 'ngoe le ho hlahisa lipontšo tse ngata ka ho khetha litsela tse fapaneng tsa ho kenya.
4. Theknoloji ea ho fetola: Ke karolo ea bohlokoa ho thekenoloji ea phetoho e sebelisetsoang ho khetha litsela tse fapaneng tsa ho kenya le ho hlahisa ho finyella ho fetola mechine e mengata.

Qualwavee fana ka li-multiplexers tsa boholo bo fokolang tse haneloang ka bongata maemong a maqhubu a DC-14GHz.Li-multiplexers li sebelisoa haholo lits'ebetsong tse ngata.
