(Q1) Definea Boolean Variable |
(A1) A Boolean variable is one that may have one of two discrete values, either Trueor False |
|
|
(Q2) Whatdoes a Truth Table show? |
(A2) A Truth Table shows the result of applying a particular logical function to allpossible combinations of inputs. |
|
|
(Q3) When is the output true for an OR Function/Gate? |
(A3) Theoutput is true for an OR gate/function when either one or both inputs are true. |
|
|
(Q4) Theoutput is true for an OR gate/function when either one or both inputs are true. |
(A4) A Boolean equation is one that expresses a Boolean output Q in terms of itsinputs X, Y, Z etc towhich one or more Boolean functions, such as OR, AND and NOT, are applied. |
|
|
(Q5) When is the output true for an AND Function? |
(A5) The output is true for an AND function if and only if all inputs are true. |
|
|
(Q6) What does a NOT Function do? |
(A6) With a NOT function the output is the inverse of the input. |
|
|
(Q7) What is a Logic Gate? |
(A7) A Logic Gate is an electronic circuit that performs a Boolean function. |
|
|
(Q8) When does an Exclusive OR (XOR) Function produce an output of True? |
(A8) An XOR Function produces an output of True if and only if one of the inputs isTrue, but not if both inputs are True. |
|
|
(Q9) When does a NAND Function produce an output which is True? |
(A9) Witha NAND gate, the output is true when any input is False. |
|
|
(Q10) When does a NOR Function produce an output which is True? |
(A10) With a NOR Function, the output is true only when all the inputs are false. |
|
|
