Boolean circuits are logic circuits consisting of various "gates" that are arranged to combine two or more bits into a single-bit output. Using the term "false" to represent an input/output that is "off" or a "0"; "true" to represent an input/output that is "on" or a "1"; and A, B, C, etc. as inputs and X as the ouput... AND gate: has two or more inputs that will result in a true output only if all of the inputs are true. If A AND B AND C are true, then X is true. OR gate: has two or more inputs that will result in a true output if any one of the inputs is true. If A OR B OR C is true, then X is true. XOR (eXclusive OR) gate: has two inputs that will result in a true output if and only if one of the two inputs is true. If A AND B are both true or both false, then X is false.
If A is true OR B is true, then X is true. NOT gate: inverts the value of a single input. If A is true, then X is false. If A is false, then X is true. Gates called NAND (NOT-AND) and NOR (NOT-OR) have a built-in NOT function for the output. You can build a very simple AND or OR gate using two switches and a bulb. If the switches are wired in series so that both must be on for the bulb to light, that is an AND gate. If the switches are wired in parallel so that either one will light the bulb, that is an OR gate. XOR is somewhat more complex, but can be simulated with two-position switches. NOT would require a relay that lights the bulb when there is no power to its coil. Some info on Boolean logic and circuits: http://en.wikipedia.org/wiki/Boolean_circuits

What are two things required to make electric current flow in a circuit?
you need an electrical supply and a load. nice and simple.
What is the function of circuit breakers and fuses?
Protection. They shut off the power to protect the equipment circuits, the main circuits and people.
What is the Difference between network and circuit?
An electrical network is an interconnection of electrical components (e.g. batteries, resistors, inductors, capacitors, switches) or a model of such an interconnection, consisting of electrical elements (e.g. voltage sources, current sources, resistances, inductances, capacitances). An electrical circuit is a network consisting of a closed loop, giving a return path for the current.An electric circuit is a path in which electrons from a voltage or current source flow. Electric current flows in a closed path called an electric circuit. The point where those electrons enter an electrical circuit is called the "source" of electrons. The point where the electrons leave an electrical circuit is called the "return" or "earth ground". The exit point is called the "return" because electrons always end up at the source when they complete the path of an electrical circuit. The part of an electrical circuit that is between the electrons' starting point and the point where they return to the source is called an electrical circuit's "load". The load of an electrical circuit may be as simple as those that power electrical appliances like refrigerators, televisions, or lamps or more complicated, such as the load on the output of a hydroelectric power generating station.
How do you use series circuit in a sentence?
This project will require a parallel circuit, not a series circuit.
The pathway taken by an electric current is a?
The term is "circuit" (from the same root as circle) An electric circuit must be uninterrupted for the current to flow. (This is why circuit-breakers are also called circuit-interruptors.)
Enter a boolean expression and drow the circuit of that boolean expression?
Construct circuit for Boolean expression (Mention out put at each step) (PÚ~ Q) Ù (P Ú Q)
How do you simplify this circuit?
To simplify a circuit you must first find a Boolean expression for the circuit and then apply Boolean algebra to take it down to the simplest form, to implement the fewest gates.
Construct a logic circuit diagram in Boolean expression?
a+C+BD+B
Is it possible to make circuit with only multiplexers?
Yes. Any basic gate's Boolean expression can be implemented using a 2:1 multiplexer and hence any combinational circuit can be implemented using only multiplexers.
What kind of math is used in circuitry?
Boolean algebra figures heavily in circuit design.
Why in computer or in any other digital circuit design the help of boolean algebra is used?
Boolean algebra is used in logic circuits. Using And, Nor, Xor and Nand gates to determine the state of an output, dependant on the condition of various inputs. Or, if you like, to make a fixed decision based on the inputs. When designing a logic circuit, it is easy to get confused by too many steps in the process to get the answer that you want. By using Boolean algebra, the steps can be rationalised and reduce to the minimum number of steps, before committing to a finished physical circuit.
Define boolean theorem?
Boolean Theory is used to make Boolean Equations easier to perform. It offers theories for solving single and multiple variables.
Why is it important for Boolean expressions to be minimized in the design of digital circuits?
1.to make circuit to be smaller hence less number of logic gate. 2.reduces propagation. 3.reduces error. 4.implementing the expression in circuit form.
a)Why do we simplify Boolean expressions?
Through Boolean algebra simplification, a Boolean expression is translated to another form with less number of terms and operations. A logic circuit for the simplified Boolean expression performs the identical function with fewer logic components as compared to its original form.
PLC ladder diagram for boolean function?
The process of converting control objectives into a ladder logic program requires structured thought. Boolean algebra provides the tools needed. You can get the product at projuktiponno
What are the three basic gates?
The package Truth Tables and Boolean Algebra set out the basic principles of logic. Any Boolean algebra operation can be associated with an electronic circuit in which the inputs and outputs represent the statements of Boolean algebra. Although these circuits may be complex, they may all be constructed from three basic devices. These are the AND gate, the OR gate and the NOT gate.
Which boolean operation is referred to as a boolean product?
AND operation is referred as a boolean product
