|combinations |(truth |table |lines).
2. |All |circuits |can |be |created |using |only |NOR |gates.
3. |You |should |never |tie |2 |outputs |of |two |distinct |circuits |together.
Which |3-input |gate |outputs |a |false |value |only |when |all |inputs |are |true? |- |CORRECT |
ANSWER✔✔-NAND
Can |you |construct |an |XOR |gate |using |only |AND/OR/NOT |gate(s)? |- |CORRECT |ANSWER✔✔-True
Which |of |the |following |statements |are |true? |- |CORRECT |ANSWER✔✔-1. |K-Map |and |Boolean |
Algebra |can |be |used |to |simplify |circuits.
2. |Equations |can |be |derived |from |K-Maps |using |SOP |and |POS.
Which |gate |on |the |list |is |considered |"functionally |complete", |which |means |that |you |can |
construct |a |NOT |gate, |an |AND |gate |and |an |OR |gate |using |a |combination |of |only |this |particular |
gate? |- |CORRECT |ANSWER✔✔-NAND

Somebody |was |asked |to |perform |an |addition |of |the |two |6-bit |signed |integers |100111 |+ |
110111 |by |calculating |the |decimal |equivalent |of |each |binary |number |and |indicating |if |
overflow |occurs. |Unfortunately, |the |papers |got |messed |up |and |now |the |person |is |struggling |to
|find |the |matching |solution. |Can |you |help |by |indicating |which |one |of |the |following |answers |is |
the |correct |one? |- |CORRECT |ANSWER✔✔--25 |- |9 |= |-34, |overflow
