Digital Multiplexer: whakaahuatanga, whakaaro, momo

He multiplexer mamati ko te pūrere ngā arorau tikanga nei hoki te tuku te mana o ngā raraunga i te maha ngā pūtake raraunga ki te hongere putanga. I roto i te meka, tenei pūrere ko te whakakā tū mamati maha. Huri i te reira i roto i taua i te pana ko te tohu multiplexer wāhi mamati ki te raina putanga kotahi.

E toru ngā rōpū o ngā kōkuhunga tenei pūrere:

• wāhitau, waehere ā-rua e whakatau nei ngā mōhiohio tāuru te hono ki te putanga;
• mōhiohio;
• tukua (gating).

Ko te iahiko integrated mamati multiplexer hua 16 He te kōkuhunga ngā mōhiohio mōrahi. Ki te titau te kōwae matapae he nui nui, i roto i nei take hanga te hanganga te rakau multiplexer pera-ka karanga o te maha maramara.

Ka taea te whakamahi multiplexer Digital mo te kōtuitui o ngā tetahi kōwae arorau, e nui te whakaiti i te maha o iahiko whakamahia i roto i te huānga arorau.

multiplexers Ture pūrere kōtuitanga hāngai:

• hanga Karnaugh mahere te mo te mahi putanga (rite ki nga uara o ngā mahi tāupe);
• Kei te tīpakohia i roto i te raupapa o te whakamahi o te ara iahiko multiplexer;
• masking te kopu hangaia, e me hāngai ki te tikanga e whakamahia ana e te multiplexer;
• Me whakaritea te kopu hua i runga i te mahere Karnaugh;
• muri kawea te whakaiti mahi motuhake mo ia wāhi o te ngohi;
• i runga i te pūtake o whakaiti nga hua e tika ana ki te hanga i te ara iahiko.

Ko te ariā nei ki te mahi. A feruri te wahi te tono taua whakaaro.

E hangaia multiplexers hangore ki te hanga i awa mamati (tuatahi) i te tere o te 2048 kbit / s o nga tohu tairitenga (kupu), kia rite ki te pai kia rite ki te raraunga o te atanga mamati ripeka-hono takere hiko o 64 kbit / ngā awa mamati tuku i runga i te whatunga IP / Itarangi me mo te faafariuraa kē aho me hononga tinana.

Ki te taea te pūrere taua tuku anō i ki 60 (i roto i te tahi mau tauira, tenei ahua i taea e atu) i kounuhia tairitenga i roto i te 1 2 ranei E1 128 ranei huinga kaitango ki wha E1. Tikanga, nga kounuhia tairitenga PM protrude rārangi he whakatinana ropu kē pūnaha whakaoho ranei kei i runga i te hongere motuhake. Ka taea te kōpeke ēnei reo takere ki 32 ranei 16 kbit / s ia teihana, whakamahia e te reira i te waehere ADPCM.

tukua multiplexers hangore ki a koe te whakamahi i hononga multicast, arā hoatu te tohu i tetahi o nga awa mamati tairitenga ranei i runga i te torutoru ētahi atu. E mea pinepine whakamahia mō te tuku i ngā hōtaka reo irirangi wā kotahi i roto i te maha o ngā wāhi rerekē.

multiplexers Optical - he whakaaro hangaia ki te mahi ki te awa raraunga mā te whakamahi i kurupae marama e rerekē te kaha tīwera wāhanga ranei pae kupenga , me te roangaru. Ko te painga o taua whakaaro ngā resilience, haumaru hangarau, tiaki ki hacking o ngā mōhiohio tuku.
