2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27

Nyob zoo sawv daws, Tam sim no peb nyob hauv lub ntiaj teb digital. Tab sis dab tsi yog digital? Puas yog nyob deb ntawm analog? Kuv pom ntau tus neeg, uas ntseeg tias cov khoom siv hluav taws xob digital sib txawv ntawm cov khoom siv hluav taws xob sib piv thiab cov analog yog pov tseg ib qho. Yog li ntawm no kuv tau ua cov lus qhia no kom paub cov neeg uas ntseeg tias digital txawv ntawm cov khoom siv hluav taws xob sib piv. Hauv kev muaj tiag cov khoom siv hluav taws xob digital thiab analog zoo ib yam, cov khoom siv hluav taws xob digital tsuas yog ib feem me me ntawm cov khoom siv hluav taws xob zoo ib yam li cov khoom siv hluav taws xob hauv ntiaj teb physics. Cov digital yog qhov txwv ntawm analog. Yeej qhov analog zoo dua li digital, vim tias thaum peb hloov cov teeb liab analog mus rau digital nws qhov kev daws teeb meem tsawg dua. Tab sis niaj hnub no peb siv digital, nws tsuas yog vim tias kev sib txuas lus digital yog yooj yim thiab tsis cuam tshuam thiab nrov nrov dua li analog. Kev khaws cov digital yog yooj yim dua li analog. Los ntawm qhov no peb tau txais qhov ntawd, Cov digital tsuas yog kev faib cais lossis qhov txwv tsawg ntawm cov khoom siv hluav taws xob sib piv hauv ntiaj teb.

Yog li hauv cov lus qhia no kuv tau ua cov txheej txheem digital yooj yim zoo li flip-flops siv cov transistors sib cais. Kuv ntseeg tias qhov kev paub dhau los xav tias koj txawv. OK. Cia peb pib nws…

Kauj ruam 1: Digital yog dab tsi ???

Digital tsis muaj dab tsi, Nws tsuas yog ib txoj hauv kev rau kev sib txuas lus. Hauv digital peb sawv cev rau txhua cov ntaub ntawv hauv ib tus (qib siab hauv Circuit lossis Vcc) thiab zeros (qis qis hauv Circuit lossis GND). Tab sis hauv digital peb sawv cev rau cov ntaub ntawv hauv txhua qhov hluav taws xob ntawm Vcc thiab GND. Ntawd yog, nws yog ib qho txuas ntxiv mus thiab cov digital yog qhov sib txawv. Txhua qhov kev ntsuas lub cev yog txuas ntxiv lossis sib piv. Tab sis tam sim no ib hnub peb txheeb xyuas, suav, khaws cov ntaub ntawv no tsuas yog hauv digital lossis daim ntawv tsis sib xws. Nws yog vim nws muaj qee qhov tshwj xeeb zoo li kev tiv thaiv suab nrov, tsis muaj chaw cia thiab lwm yam.

Piv txwv rau digital thiab analog

Xav txog qhov hloov pauv SPDT, Nws ib sab txuas nrog Vcc thiab lwm yam rau GND. Thaum twg, peb txav qhov hloov ntawm ib txoj haujlwm mus rau lwm qhov ces peb tau txais cov txiaj ntsig zoo li Vcc, GND, Vcc, GND, Vcc, GND, … Qhov no yog lub cim digital. Tam sim no peb hloov qhov hloov pauv los ntawm potentio-meter (qhov sib txawv resistor). Yog li, thaum tig qhov sojntsuam ces peb tau txais qhov hloov pauv tas li ntawm GND rau Vcc. Qhov no sawv cev rau cov teeb liab analog. OK, tau txais …

Kauj ruam 2: Latch

Latch yog lub cim xeeb tseem ceeb khaws cia hauv cov xov tooj cua digital. Nws khaws ib qho me ntsis ntawm cov ntaub ntawv. Nws yog chav me me ntawm cov ntaub ntawv. Nws yog hom kev hloov pauv tsis nco vim tias nws cov ntaub ntawv khaws cia ploj mus thaum lub zog tsis ua haujlwm tshwm sim. Tsuas yog khaws cov ntaub ntawv kom txog thaum lub hwj chim muaj. Latch yog lub hauv paus tseem ceeb hauv txhua qhov kev nco flip-flop.

Cov vis dis aus saum toj no qhia txog lub latch uas txuas rau ntawm lub khob cij.

Daim duab qhia hluav taws xob saum toj no qhia qhov yooj yim Circuit Court. Nws muaj ob lub transistors, txhua lub hauv paus transistor txuas nrog rau lwm tus neeg sau khoom kom tau txais cov lus tawm tswv yim. Qhov kev tawm tswv yim no pab khaws cov ntaub ntawv hauv nws. Cov ntaub ntawv tawm tswv yim sab nraud tau muab rau lub hauv paus los ntawm kev siv cov ntaub ntawv teeb liab rau nws. Cov ntaub ntawv no teeb liab hla lub hauv paus qhov hluav taws xob thiab cov transistors txav mus rau lub xeev ruaj khov tom ntej thiab khaws cov ntaub ntawv. Yog li nws tseem paub tias yog ob-ruaj khov Circuit. Txhua tus tiv thaiv tau muab los txwv qhov ntws tam sim no mus rau lub hauv paus thiab tus neeg sau khoom.

Kauj Ruam 3: D Flip-flop & T Flip-flop: Theory

Cov no yog cov flip-flops feem ntau siv tam sim no ib hnub. Cov no yog siv nyob rau hauv feem ntau ntawm cov digital circuits. Ntawm no peb tham txog nws txoj kev xav ib feem. Flip-flop yog lub tswv yim nco khaws cia. Lub latch tsis siv rau hauv kab hluav taws xob, tsuas yog siv lub flip -flops. Lub latch clocked yog flip-flop. Lub moos yog lub teeb liab siv tau. Tsuas yog lub flip-flop nyeem cov ntaub ntawv ntawm lub tswv yim thaum lub moos nyob hauv cheeb tsam nquag. Yog li lub latch tau hloov pauv mus rau flip-flop los ntawm kev ntxiv lub moos hauv ntej ntawm lub latch. Cov no yog hom sib txawv qib ua rau thiab ntug ua rau. Ntawm no peb tham txog ntug kev tshwm sim vim nws feem ntau yog siv hauv digital circuits.

D tig-flop

Hauv qhov flip-flop qhov tso tawm yog theej cov ntaub ntawv nkag mus. Yog tias cov tswv yim yog 'ib qho' ces cov zis ib txwm yog 'ib qho'. Yog tias cov tswv yim yog 'xoom' ces tso tawm ib txwm 'xoom'. Cov lus tseeb muab hauv daim duab saum toj no. Daim duab qhia hluav taws xob qhia qhov tsis sib xws d flip flop.

T tig-flop

Hauv qhov flip-flop cov ntaub ntawv tso tawm tsis hloov pauv thaum lub tswv yim nyob ntawm 'xoom' lub xeev. Cov ntaub ntawv tso tawm toggles thaum cov ntaub ntawv tawm tswv yim yog 'ib qho'. Qhov ntawd yog 'xoom' rau 'ib' thiab 'ib' rau 'xoom'. Qhov tseeb rooj muab saum toj no.

Kauj Ruam 4: D Flip-Flop

Daim duab hluav taws xob saum toj no qhia pom D-flip-flop. Nws yog qhov ua tau. Ntawm no 2 transistors T1 thiab T2 tau ua haujlwm zoo li lub latch (tau tham yav dhau los) thiab transistor T3 yog siv rau tsav LED. Txwv tsis pub qhov tam sim no kos los ntawm LED hloov pauv qhov hluav taws xob ntawm qhov tso tawm Q. Lub transistor thib plaub yog siv los tswj cov ntaub ntawv nkag. Nws hla cov ntaub ntawv tsuas yog thaum nws lub hauv paus yog qhov muaj peev xwm loj. Nws lub hauv paus hluav taws xob tau tsim los ntawm qhov sib txawv ntawm Circuit tsim los ntawm kev siv lub tshuab hluav taws xob thiab cov tiv thaiv. Nws hloov pauv cov tswv yim square yoj moos teeb liab mus rau qhov ntse. Nws tsim cov transistor rau ntawm ib qho nkaus xwb. Qhov no yog ua haujlwm.

Cov vis dis aus qhia nws txoj haujlwm thiab kev xav.

Yog xav paub ntxiv txog nws ua haujlwm, Thov mus ntsib kuv BLOG, txuas hauv qab no, 0creativeengineering0.blogspot.com/2019/03/what-is-d-flip-flop-using-discrete.html

Kauj Ruam 5: T Flip-Flop

T flip-flop yog tsim los ntawm D flip-flop. Txog qhov no, txuas cov ntaub ntawv nkag mus rau cov txiaj ntsig ntxiv Q '. Yog li Nws tau tso tawm lub xeev hloov pauv (hloov pauv) thaum siv lub moos. Daim duab qhia hluav taws xob tau muab rau saum toj no. Lub Circuit Court muaj ib qho ntxiv capacitor thiab resistor. Lub tshuab hluav taws xob tau siv los qhia kev lag nruab nrab ntawm cov zis thiab cov tswv yim (latch transistor). Txwv tsis pub nws ua haujlwm. Vim tias peb txuas cov transistor tso rau nws lub hauv paus nws tus kheej. Yog li tsis ua haujlwm. Nws ua haujlwm tsuas yog thaum ob qhov hluav taws xob muaj lub sijhawm qeeb. Qhov kev lag luam no tau qhia los ntawm tus capacitor no. Lub tshuab hluav taws xob no tawm los ntawm kev siv tus tiv thaiv los ntawm Q cov zis. Lwm qhov ntse nws tsis hloov pauv. Cov Din txuas nrog rau cov txiaj ntsig ntxiv Q 'rau muab lub toggle input signals. Yog li los ntawm cov txheej txheem no ua haujlwm tau zoo heev.

Cov vis dis aus saum toj no tseem piav qhia nws ua haujlwm thiab nws yog kev xav.

Kauj Ruam 6: Cov phiaj xwm yav tom ntej

Ntawm no kuv tau ua tiav cov txheej txheem digital yooj yim (cov kab sib txuas sib txuas) siv cov transistors sib cais. Kuv nyiam cov transistor raws tus qauv. Kuv tau ua qhov tsis sib xws 555 qhov project hauv ob peb lub hlis tom qab. Ntawm no kuv tsim qhov flip-flops rau kev txiav txim siab DIY lub computer siv transistors. Lub computer tsis sib xws yog kuv npau suav. Yog li hauv kuv txoj haujlwm tom ntej no kuv ua qee yam ntawm cov suav thiab txiav txim siab los ntawm kev siv cov transistors sib cais. Nws yuav los sai sai no Yog koj nyiam nws, Thov pab txhawb nqa kuv. OK. Ua tsaug.
