JK-jefa-Flop. Ka'idar aiki, funtsktsionalnye kewaye gaskiya tebur

A jawo shi ne mai sauki dijital na'ura. Yana yana da biyu jihar zaman lafiya. Daya daga cikin su an saita zuwa "1", da kuma wani - "0".

A Hanyar ganin na ma'ana sadarwa bambanta da wadannan iri na'urorin da aka ambata: JK-jefa-Flop, RS-jefa-Flop, T-jefa-Flop, D-jefa-Flop , da dai sauransu ...

A batu na mu tattaunawa a yau ne wani irin inji JK. Sun bambanta daga RS-na'urorin da cewa a lokacin da amfani da shigar da bayanai haramta RS-triggers, adana inverted a cikin bayanai.

Gabatar da hankali da Jump tebur, abin da ya bayyana aikin na JK-jefa-Flop. A minimizing Kata Carnot samu halayyar lissafi ga na'ura in tambaya: Q (t + 1) = K't de Qt V JT Q't.

Tebur ya nuna cewa, jihar na da na'urar da aka kaddara ba kawai da dabi'u na bayanai ga bayanai J kuma K, amma kuma da jihar fitarwa de Qt, wanda a baya m da JK-jefa-Flop. Wannan ba ka damar gina wani aikin makirci na irin wannan na'urorin a kan biyu-mataki inji RS irin. JK-na'urorin ne synchronous da asynchronous.

Domin da zane na JK-jefa-Flop RS na biyu-mataki irin synchronous na'urorin da ake bukata domin haɗa biyu mataki RS feedbacks inji jimloli zuwa bayanai na AND ƙofofin ta mataki na farko.

The aiki manufa na JK-jawo: Idan bayanai (J kuma K) na'urar amfani da shigar da matakin na sifili, sa'an nan da fitarwa na AND-BA (1 da 2) an saita zuwa daya matakin, da kuma JK-jefa-Flop za ta riƙe da matsayi. Alal misali, Q zai zama daidai da dabaru sifili, Q '- ma'ana naúrar. A wannan yanayin, sa'ad da alamar hayaƙin J kuma C, sunã daidaita da mai ma'ana naúrar AND-HE1 shigar da kafa da kuma dabaru sifili, bi da bi, wani dabaru daya matakin a mashiga ruwa na farko T-jefa-Flop. Lokacin da cire agogon siginar (C sifili) jiha da na'urar da T-type dabaru-sifili matakin fitarwa daga DA = HE3 a wuce zuwa shigar da biyu T-jefa-Flop. A sakamakon JK-jefa-Flop sauya zuwa dabaru-daya jiha (wanda idan Q ne daidai da daya, kuma Q 'ne ya daidaita da sifili). Yanzu, idan shigar da jefa-Flop (K da kuma C) wata sigina daidai da dabaru daya, da fitarwa daga DA-HE2 ma'ana sifili tabbatar da farko T-jefa-Flop a sifili jihar. Bayan cire agogon sigina daga cikin fitarwa na AND-HE4 dabaru sifili za a wuce zuwa shigar da biyu automaton na da irin T, da kuma JK-jefa-Flop ne switched zuwa wani dabaru sifili jihar.

A cikin zane na hadaddun dabaru haihuwarka ake bukata domin daban-daban iri na'urorin. Saboda haka m zuwa tsirar duniya irin na'ura da za a iya amfani da daban-daban halaye da kuma gyare-gyare. A Hadakar kewaye zane mafi yadu amfani synchronous D- da JK-jefa-flops. A lantarki kwakwalwa yadu amfani da dijital JK-type inji tare da kungiyar J, K da kuma ƙarin shigarwa R, S-bayanai. Kowace kungiya ne united tare da cewa ba ka damar fadada ma'ana yiwuwa kuma JK-jefa-Flop.

Atomatik na'urorin na irin wanda aka yi amfani a cikin shiri na counters (kwamfuta kumburi cewa ya yi aikin asusun code da adanar da kidaya yawan sakonni). Alal misali, hoton na nuna wani mai counter a kan JK-jefa-flops. A tsarin kungiyar na binary counter da layi daya canja wuri ne sauƙin idan sun gina a kan JK-type na'urorin tare da saka dabaru abubuwa I.

Har ila yau, wadannan triggers an yi amfani da shiri na miƙa rajista.

Shift rajista - ne nodes yin biya diyya binary bayanai ga dama da hagu na littãfi bisa ga ikon sakonni.
