The Logic OR Function function states that an output action will become TRUE if either one “OR” more events are TRUE, but the order at which they occur is unimportant as it does not affect the final result. For example, A + B = B + A.

What is the function of logic gates?
Logic gates are used to make decisions so that electrical outputs only ‘turn on’ when the correct logic sequence has been applied. Each logic gate has a name that helps to describe how different inputs will determine the possible outputs .
What are logic equations?
LOGIC EQUATION is a reserved word to specify a logic proposition, name must be provided by the user, it must follow the rules of any constraint name.
What is another way of representing logic functions?
In Boolean algebra the Logic AND Function follows the Commutative Law which allows a change in position of either variable. The AND function is represented in electronics by the dot or full stop symbol ( . ) Thus a 2-input (A B) AND Gate has an output term represented by the Boolean expression A. B or just AB.
What is Boolean function with example?
A Boolean function is a function that has n variables or entries, so it has 2n possible combinations of the variables. These functions will assume only 0 or 1 in its output. An example of a Boolean function is this, f(a,b,c) = a X b + c. These functions are implemented with the logic gates.
What is meant by Boolean function?
In mathematics, a Boolean function is a function whose arguments and result assume values from a two-element set (usually {true, false}, {0,1} or { -1,1}).Boolean functions are the subject of Boolean algebra and switching theory.
What is logic in math examples?
For example, 1 + 2 = 3 and 4 is even are clearly true, while all prime numbers are even is false. In logic we are often not interested in these statements themself, but how true and false statements are related to each other.

What are logic diagrams?
logic diagram A diagram that displays graphically, by interconnection of logic symbols, the digital design of a logic circuit or system. A Dictionary of Computing.
How do you write a logic statement in computer science?
Logic gate circuits can be expressed as a circuit diagram, or as a written logic statement. e.g. Z = ((NOT A) AND (A OR B)) OR (A OR B) Each exam board will have their own preference on how to express these written statements, but the principles remain the same.
What is called a logical multiplication?
[′läj·ə·kəl məl·tə·plə′kā·shən] (mathematics) The multiplicative binary operation of a Boolean algebra.
What is a truth table function?
A truth table is a breakdown of a logic function by listing all possible values the function can attain. Such a table typically contains several rows and columns, with the top row representing the logical variables and combinations, in increasing complexity leading up to the final function.
How do you write a Boolean function from a truth table?
Product-Of-Sums, or POS, Boolean expressions may also be generated from truth tables quite easily, by determining which rows of the table have an output of 0, writing one sum term for each row, and finally multiplying all the sum terms. This creates a Boolean expression representing the truth table as a whole.
What is logic functions in digital electronics?
The Logic OR Function function states that an output action will become TRUE if either one “OR” more events are TRUE, but the order at which they occur is unimportant as it does not affect the final result.
How do you write a Boolean function in JavaScript?
var a1 =”true”; var a2 =”false”; Boolean() function in JavaScript: Boolean function returns the boolean value of variable. It can also be used to find boolean result of a condition, expression etc. Note: A variable or object which has value are treated as true boolean values.
How do logic gates implement Boolean functions?
Logic gates implementation or logic representation of Boolean functions is very simple and easy form. The implementation of Boolean functions by using logic gates involves connecting output of one logic gate to the input of another gate. Commonly used Logic Gates are: AND, OR, NAND and NOR gates.
How do you write a logic statement?
Logical statements have two parts, a hypothesis that presents facts that the statement needs to be true, and a conclusion that presents a new fact we can infer when the hypothesis is true. For a statement to be always true, there must be no counterexamples for which the hypothesis is true and the conclusion is false.
What are the four basic logic operations?
Elementary algebra has four operations, addition, subtraction, multiplication, and division, but Boolean algebra has only three operations: AND — a binary operator; the result is 1 if and only if both operands are 1; otherwise the result is 0. We will use ‘⋅’ to designate the AND operation.
How many logics are there?
The four main logic types are: Informal logic. Formal logic. Symbolic logic.
How are logic diagrams used?
Logic diagrams have many uses. In the solid state industry, they are used as the principal diagram for the design of solid state components such as computer chips. They are used by mathematicians to help solve logical problems (called boolean algebra).
How do you make a logic gate?
Simple Basic Digital Logic Gates
Simple digital logic gates can be made by combining transistors, diodes and resistors with a simple example of a Diode-Resistor Logic (DRL) AND gate and a Diode-Transistor Logic (DTL) NAND gate given below.
What does an AND gate do?
The AND gate is a basic digital logic gate that implements logical conjunction (∧) from mathematical logic – it behaves according to the truth table above. A HIGH output (1) results only if all the inputs to the AND gate are HIGH (1). If none or not all inputs to the AND gate are HIGH, LOW output results.
