Dvejetainių skaičių sudėties schema
Naudojantis operacijas AND, OR ir NOT atliekančiais loginiais elementais, galima parodyti, kaip sukurti schemą dviem dvejetainiams skaičiams sudėti.
Žinome dviejų dvejetainių skaičių a ir b sudėties taisykles (žr. lentelę). Matome, kad dviejų įėjimo signalų, lygių 1, rezultatas yra dviženklis dvejetainis skaičius. Todėl dvejetainių skaičių sudėties schemoje turi būti ne tik du įėjimo, bet ir du išėjimo signalai.
| a | b | a + b |
|---|---|-------|
| 0 | 0 | 0₂ |
| 0 | 1 | 1₂ |
| 1 | 0 | 1₂ |
| 1 | 1 | 10₂ |
Naudodamiesi programa *Crocodile Technology*, sukurkite dvejetainių skaičių sudėties schemą. Panagrinėkite, kaip ji veikia. Tai labai svarbu, norint geriau suvokti kompiuterio veikimo principus. Schemoje vienetu žymimą signalą (pvz., aukštąją įtampą) galima įsivaizduoti kaip loginę reikšmę tiesa (TRUE), nuliu žymimą signalo nebuvimą – kaip loginę reikšmę netiesa (FALSE).
**Pavyzdžiai:**
* 0 + 0 = 0₂ (abu išėjimo signalai 0)
* 1 + 0 = 1₂ (pirmos skilties išėjimo signalas 1, antrosios – 0)
* 0 + 1 = 1₂ (pirmos skilties išėjimo signalas 1, antrosios – 0)
* 1 + 1 = 10₂ (pirmos skilties išėjimo signalas 0, antrosios – 1)
## 7*. Uogienė
Petras, Bronius ir Marytė pasiliko namuose vieni. Grįžusi mama pastebėjo, kad vaikai suvalgė uogienę. Į jos klausimą, kas tai padarė, vaikai atsakė:
a) Petras: „Aš nevalgiau. Marytė taip pat nevalgė.“;
b) Bronius: „Marytė tikrai nevalgė. Petras suvalgė.“;
c) Marytė: „Bronius meluoja. Tai jis suvalgė.“
Parenkite vaikų teiginių teisingumo lentelę ir atsakykite, kas suvalgė uogienę. Alyvine spalva pažymėtiems langeliams užpildyti pritaikykite tinkamas formules ir funkcijas. Žinoma, kad du vaikai mamai nemelavo, o trečias – vieną kartą pamelavo.
