If both the cables are ON or we can say representing 1 in computer language, then... OR Gate. Our gate accepts two wires. If one of them is 1, the output will be 1. Both inputs of the OR gate are high. NOT Gate.. The logic gate truth table or truth tables used for electronic logic gates circuits including the AND, NAND, OR, NOR and exclusive OR circuits Input and Outputs of Logic gates in only two levels called TRUE and FALSE, or HIGH and LOW, or ON and OFF, or very popular 0 and 1. High (1 or TRUE or ON) means +5v. LOW(0 or FALSE or OFF) means 0v (or -ve supply) This 2 level logic also called Positive and Negative Logic. AND GATE. AND gate has two or more than two inputs and only one Output . The NOT gate is also known as an inverter because the output is the exact opposite of the input. It has one input and one output. The two possibilities are written out in the table below. Tables listing all logical possibilities like this are known as truth tables
Truth Tables. Truth tables are used to help show the function of a logic gate. If you are unsure about truth tables and need guidence on how go about drawning them for individual gates or logic circuits then use the truth table section link. Truth Tables A truth table shows, for each combination of inputs, what the output will be. Like logic gates, a 0 in the table represents FALSE, while 1 represents TRUE. An AND gate is represented in the truth..

Basic logic gates are often found in circuits such as safety thermostat, push-button lock, automatic watering system, light-activated burglar alarm and many other electronic devices. One of the primary benefits is that basic logic gates can be used in a mixture of different combinations if the operations are advanced
Logic circuits include such devices as multiplexers, registers, arithmetic logic units, and computer memory, all the way up through complete microprocessors, which may contain more than 100 million gates. In modern practice, most gates are made from MOSFETs. Compound logic gates AND-OR-Invert and OR-AND-Invert are often employed in circuit design because their construction using MOSFETs is simpler and more efficient than the sum of the individual gates. In reversible logic. AND Gate Truth Table. AND gate is a basic gate with multiple inputs and a single output. This gate has its output high only if all its inputs are one, failing which the output will be zero as shown by the truth table.

Logic gates are the basic building blocks used typically in the field of Digital Electronics. Each gate performs a specific logic function behind which there is an equivalent transistor based electronic circuit. An engineer uses logic symbols to focus on the logic expression, instead of. . 1. NOR Gate. The NOR gate is a dc combination of OR gate with the not gate. The output of NOR gate is totally opposite of the output of the OR gate. In NOR gate, the output to be high (logic 1) if all the inputs are low (0); if one or all input is high (*1), a low output (0) result will display
Since reversible logic gates are symmetric with respect to the number of inputs and outputs, we can represent them in ways other than the truth table, that emphasizes this symmetry. We have already encountered the reversible NOT gate, whose truth table was given in tables (2). We could also write this in the form of a matrix, or as a graphic Logic Gates Basics Truth table A logic gate may have one or more inputs, but only one output. The relation between the possible values of input and output signals are expressed in a table which is called the truth table. Thus, the truth table of a logic gate is a table that shows all possible input combinations and the corresponding. Figure 1. Diagram and truth table for AND / OR logic gates. Of course, AND and OR are just two examples of fundamental logic gates. But a curious logic gate to explore further is the NAND gate (NOT AND) - because it has a rather special property: 'functional completeness' Symbol of the Logic Gate. For each gate, the input or inputs are on the left of the symbol. The output is on the right. The Truth Tables. The function of a logic gate can be shown by using the Truth tables. A truth table lists all possible input together with the corresponding output
Truth table is a table which shows the shows the output state depending upon the possible combination of input states.It shows the function of a logic gate. OR Gate: An OR Gate is an electronic circuit that gives a true output (1) if one or more of its input are true Construct SOP from a Truth Table: There are certain rules that you need to follow while constructing a logic circuit from any truth table. These rules for the SOP circuits are given below: A circuit for a truth table with N input columns can use AND gates with N inputs, and each row in the truth table with a '1' in the output column. There are 7 different logic gates, these are, OR, NOR, AND, NAND, XOR, NXOR and NOT. All of the possible outcomes of each logic gate can be shown by using a truth table. Off is represented by 0 and on is represented by 1. In the truth table, 'A' and 'B' are the inputs and 'Q' is the outcome. An OR gate will give the following out comes

Its logic symbol and truth table are shown in fig. Its logic function and truth table are just the reverse of those for XOR gate. This gate has an output 1 if it's both inputs are either 0 or 1. In other words, for getting an output, it's both inputs should be at the same logic level of either 0 or 1 Table 2: Truth Table of 3-input AND Gate. The AND gate may be thought of as an electrical circuit in which the switches are connected in series. Lamp will glow (output will be present) only when all the switches are closed The truth table reflects the fundamental property of the OR gate: the output of A OR B is 1 if input A or input B is 1. Creating logic gate circuits. Multiple logic gates can be connected to produce an output based on multiple inputs.
