NOR, NAND, XOR, XNOR Gates Flashcards
The _____ is represented by the rounded triangle symbol with the NOT function.
NOR gate
What is the difference between the NOR gate and the OR gate.
The NOR gate is like the OR gate except for the NOT function.
The NOT function causes the OR gate output to do what?
The NOT function causes the OR gate output to invert.
The output that would be LOW from an OR gate is HIGH from a NOR gate. The output that would be HIGH from an OR gate is LOW from a NOR gate.
The NOT function causes the OR gate to be a NOT-OR gate, a.k.a?
NOR Gate. (NOT-OR)
The function of a NOR gate is to determine when at least one input condition is ____. A HIGH output is available when all the inputs are LOW.
The function of a NOR gate is to determine when at least one input condition is TRUE. A HIGH output is available when all the inputs are LOW.
In this circuit, if neither S1 or S2 is ON, the light is ON. This best demostrates the ____ gate
NOR
When ALL inputs are LOW, the NOR gate produces a _____ output.
When ALL inputs are LOW, the NOR gate produces a HIGH output.
If any input is HIGH, the NOR gate produces a _____ output.
If any input is HIGH, the NOR gate produces a LOW output.
The _____ gate is represented by the rounded rectangle symbol and the NOT function.
The NAND gate is represented by the rounded rectangle symbol and the NOT function.
The NAND gate is like the AND gate except for the NOT function. The NOT function causes the AND gate output to do what?.
The NAND gate is like the AND gate except for the NOT function. The NOT function causes the AND gate output to invert.
The output that would be HIGH from an AND gate is also _____from a NAND gate.
The output that would be HIGH from an AND gate is LOW from a NAND gate.
The output that would be LOW from an AND gate is HIGH from a NAND gate.
The NOT function causes the AND gate to be a NOT-AND, aka what?
NAND Gate
A LOW output is only available when all the inputs are _____.
A LOW output is only available when all the inputs are HIGH.
When ALL inputs to the NAND gate are HIGH or TRUE, the gate produces a _____ output.
When ALL inputs to the NAND gate are HIGH or TRUE, the gate produces a LOW or FALSE output.
If any input is LOW with a NAND gate, the gate produces a ______ output.
If any input is LOW witha NAND gate, the gate produces a HIGH output.
The _______ gate is represented by the symbol shown below.
Exclusive OR (XOR) gate
The function of an XOR gate is to produce a HIGH output when an _____ number of inputs are _____.
The function of an XOR gate is to produce a HIGH output when an odd number of inputs are HIGH.
When an ODD number of inputs are HIGH, the gate produces a ____ output.
When an ODD number of inputs are HIGH, the gate produces a HIGH output.
If ALL inputs are LOW or an EVEN number of inputs are HIGH, the gate produces a _____ output.
If ALL inputs are LOW or an EVEN number of inputs are HIGH, the gate produces a LOW output.
What kind of gate is this?
The exclusive-NOR (XNOR)
The bubble on the output of the XNOR gate indicates that XNOR gate operates just the opposite of the _____ gate.
The bubble on the output of the XNOR gate indicates that XNOR gate operates just the opposite of the XOR gate.
The function of an XNOR gate is to produce a ____ output when the same logic level is present on both inputs.
The function of an XNOR gate is to produce a HIGH output when the same logic level is present on both inputs.
If the logic levels of the inputs are opposite, the gate produces a _____ output.
If the logic levels of the inputs are opposite, the gate produces a LOW output.
