The output of which of the following logic gate is high when one or both of the input is low :
In digital electronics, a NAND gate (NOT-AND) is a logic gate which produces an output which is false only if all its inputs are true; thus its output is complement to that of an AND gate. A LOW (0) output results only if all the inputs to the gate are HIGH (1); if any input is LOW (0), a HIGH (1) output results.
Which of the following gate can be build using a single transistor?
Answer :- d
Solution :- A transistor can be used as a switch. That is, when base is low collector is high (input zero, output one) and base is high collector is low (input 1, output 0).
If the input to a NOT gate is A and the output is X, then :
The correct answer is: X =
How many of the inputs of a 4 input AND gate must be HIGH in order for the output of the logic gate to go HIGH?
The correct answer is: all 4
The output of a logic gate is high when all its inputs are at logic 0. The gate can be :
The correct answers are: NOR, XNOR, NAND
When simplified with boolean algebra, the expression (x + y)(x + z) simplies to :
The correct answer is: x + yz
Which gates are required to build an exclusive OR (XOR) gate?
The correct answers are: OR, AND, NOT
The boolean expression of an OR gate is _______
An OR gate gives the result as 1 if any one of the inputs is one.
Its expression is A + B.
An OR gate gives a 0 only if both the inputs are 0.
The boolean expression is equivalent to :
The correct answers are:
Choose the correct options :
The correct answers are: The boolean expression of an AND gate followed by an inverter is same as the boolean expression for a NAND gate., The boolean expression for an OR gate followed by a NOT gate is same as that for a NOR gate, No two basic logic gates have the same boolean expression
