T Flip-flop. Molao-motheo oa ho sebetsa, oa potoloho tshebetso

Tsosang - e sesebediswa e bonolo ke mochini ditsitithale. Ho na le e re tse peli tsa botsitso. E 'ngoe ea maemo ana abetsoe boleng le "1"' me e mong "0". boemo sesebediswa, 'me boleng ba boitsebiso boo binary e bolokoa ho eona, ea ka matshwao a medumo khumo ikemiselitse: Direct le inverted. Tabeng ea moo ka ho toba ka 'nang khumo Ho thehoa, e leng tšoana le sa utloahalang e mong, ka nako eo puso ea phetlhwang-flop bitsoa unit trust (monyetla ka khumo inverted tšoana le e utloahalang lefela). Ha khumo otlolohileng ha e ka 'nang, moo boemo bo tsosang o bitsoa lefela.

Lintho tse tsosang litakatso tse classified ke likarolo tse latelang:

1. Ka mokhoa oa ho ngola lesedi (synchronous le tshielano).

2. Ha ho tlhahiso leseding taolo (lipalo-palo, matla, le 'ngoe-sethaleng, multistage).

3. E le ho hlokomela tsa dikgokelo utloahalang (JK-phetlhwang-flop, RS-ho etsa hore T Flip-flop, D-phetlhwang-flop le mefuta e meng).

The entsprechen o ka sehloohong oa mefuta eohle ea lintho tse tsosang litakatso tse: lebetsoeng le nako ea pontšo input, ho lieha nako e hlokehang bakeng sa ho switjha ho phetlhwang-flop, le ka ho lumella tshebetso nako.

Sehloohong sena, a re ke re bua mabapi le mofuta ona wa sesebediswa, kamoo - T phetlhwang-flop. lintho tse tsosang litakatso jwalo na feela lesedi le nngwe (T) input, eo e bitsoa tshephile input. Ho fetola isostoyanie eona ka mor'a kenoa ho count ya (T) input ea e mong le pontšo taolo.

Ho ea ka tafole phetoho, molao oa tšebetso ea joalo phetlhwang-flops e hlalositsoeng ke abel bath: Q (sa t + 1) = TtQ't V T'tQt. From abel ho e latelang le hore ha o etsa kopo ya monyako (T) ke mabaka a lefela, e T phetlhwang-flop tla a boloke boemo ba lona jwalo ka unit trust pulse length khumo felisoa.

Tafole e bontša hore T-phetlhwang-flop etsa go tlaleletsa sebetsa, 'me sena se fella ka hore e le sehlooho sa e thunye ena bala, lesedi lona (T) input-tshephile input. Boemo pontšo ka input tsa latch ho bonahala habeli nako le nako ho feta ho khumo lona (Q). Ka lebaka leo, e T-phetlhwang-flop sebelisoa e le maqhubu a divider.
