What is the formula for NOR gate?
If we say $Y$ is our final output, then the equation becomes $\overline {A + B} = Y$. This equation is called the Boolean expression for NOR gate. The output of NOR gate can be only high when both the inputs are low because in this gate, an OR gate is followed by a NOT gate.
What is a NOR gate equivalent to?
A NOR gate is equivalent to an inverted-input AND gate. An OR gate is equivalent to an inverted-input NAND gate.
What is the symbol of NOR gate?
The ANSI symbol for the NOR gate is a standard OR gate with an inversion bubble connected. The bubble indicates that the function of the or gate has been inverted.
What is the Boolean expression for a three and gate?
The 3-input Logic AND Gate
| Symbol | Truth Table | |
|---|---|---|
| 3-input AND Gate | 1 | 0 |
| 1 | 0 | |
| 1 | 1 | |
| Boolean Expression Q = A.B.C | Read as A AND B AND C gives Q |
What will be the Boolean expression for an inverter logic gate where input is A and output is G?
What will be the Boolean expression for an inverter logic gate, where input is A and output is G? Because output is the inversion of the input A. ∴ G = Ā.
What is Exclusive NOR gate?
An XNOR gate (sometimes referred to by its extended name, Exclusive NOR gate) is a digital logic gate with two or more inputs and one output that performs logical equality. The output of an XNOR gate is true when all of its inputs are true or when all of its inputs are false.
What is NOR logic gate?
A NOR gate is a logic gate which gives a positive output only when both inputs are negative. Like NAND gates, NOR gates are so-called “universal gates” that can be combined to form any other kind of logic gate.
What is the Boolean expression for XNOR gate?
An XNOR gate is also called exclusive NOR gate or EXNOR gate. In a two-input XNOR gate, the output is high (logic 1 or true) when two inputs are the same. In Boolean expression, the term XNOR is represented by the symbol (⊙) and the Boolean expression is represented as Y = A ⊙ B.
What is an example of a Boolean expression?
Boolean Expression. A boolean expression is an expression that has relational and/or logical operators operating on boolean variables. Relational operators are: Logical operators are: Examples of Boolean expression: Most C++ compilers will treat any nonzero number as true and will treat zero as false.
