Mi sembra un esercizio assurdo...
Comunque tieni presente che
$I\oplus A=\bar{A}$
e
$0\oplus A=A$

oltre, ovviamrìente, ai teoremi di DeMorgan

Ho provato a risolvere l'esercizio usando le tue indicazioni ma non riporta. Allego testo, esercizio e soluzione:

Semplificare come somma minima la seguente funzione

logica:
[unparseable or potentially dangerous latex formula]
[unparseable or potentially dangerous latex formula]

Risultato (da soluzione): $\overline X\cdot Y\cdot Z$

Magari una dritta... grazie

Per 'somma diretta' intendi Or esclusivo (XOR)?

[unparseable or potentially dangerous latex formula]

[unparseable or potentially dangerous latex formula]

[unparseable or potentially dangerous latex formula]

$\bar{X}+W+ X\cdot \bar{W} =$

Ultimissima domanda spero :mrgreen:

Quando si ha nell'espressione la somma diretta tra due numeri si applicano delle proprietà ad esempio:
$A\oplus B=A\cdot\bar{B}+\bar{A}\cdot B$

Mentre con più termini come ad esempio:
[unparseable or potentially dangerous latex formula]

come si dovrebbe procedere?

Grazie ancora!

[quote="g.schgor"] $A \cdot B +A \cdot B \cdot D =$
$A \cdot B \cdot I +A \cdot B \cdot D =$
[unparseable or potentially dangerous latex formula]
$A \cdot B \cdot D +A \cdot B \cdot \bar{D} =$
[unparseable or potentially dangerous latex formula]
$A \cdot B \cdot I =$
$A \cdot B$

Perfetto credo di aver capito, grazie infinite!

Ultima cosa. In questi 2 passaggi di due esercizi diversi cosa applica?

1)
[unparseable or potentially dangerous latex formula]

2)
$\bar{A}+A\cdot B\cdot \bar{C}=\bar{A}+B\cdot\bar{C}$

Non riesco a seguiti, negli esercizi si semplifica la

ma anche moltiplicando per la costante non riesco

No, questo è un caso già minimizzato.

Mi riferivo al caso $A \cdot B +A \cdot B \cdot D$

Moltiplicare per la costante ci sono ma in seguito come viene effettuato quel raggruppamento? Nell'equazione scompare una

:

$A\cdot B\cdot \bar{C}+\bar{A}=$

[unparseable or potentially dangerous latex formula]

Come si va avanti?
