# And gate and or gate

Gates and logic networks gates □gate: a simple electronic circuit (a system) that realizes a logical operation ▫ the direction of information flow is from the input terminals to the output terminal ▫ the number of input and output terminals is finite and they carry binary-valued signals (ie, 0 and 1) ▫ the transformation of. Logic gate simulator a free, simple, online logic gate simulator investigate the behaviour of and, or, not, nand, nor and xor gates select gates from the dropdown list and click add node to add more gates drag from the hollow circles to the solid circles to make connections right click connections to delete them. Both nand and nor gates are universal in the sense that any other gate can be built from them to build an inverter from nand, simply connect the two inputs of the nand together and use this junction as input of the inverter therefore an and gate can be realized simply as a nand followed by another nand with 2. There are total 7 logical gates:- and, or, not, nand, nor, xor, xnor among all the gates, and, or & not gate are basic gates, because these three gates have basic operation or gate is just a sum operation, ie y= a+b and gate is just a multipli. Logic gates process signals which represent true or false normally the positive supply voltage +vs represents true and 0v represents false other terms used for the true and false states are shown in the table, it is best to be familiar with them all gates are identified by their function: not, and, nand, or, nor, ex-or and. In this instructable, we are going to construct not, and, or gates using nand gates only in the next steps, we will get into boolean algebra and we will derive the. Gates are basic circuits that have at least one (and usually more) input and exactly one output input and output values are the logical values true and false in computer architecture it is common to use 0 for false and 1 for true gates have no memory the value of the output depends only on the current value of the inputs.

Boolean functions may be practically implemented by using electronic gates the following points are important to understand electronic gates require a power supply gate inputs are driven by voltages having two nominal values, eg 0v and 5v representing logic 0 and logic 1 respectively the output of a gate. As we noted earlier, we use the notation of boolean algebra when these operations are implemented in computers for each elementary boolean operation there is an associated gate symbol: a diagram which represents the electrical components used to implement the operation: the and gate: the or gate: the not gate. Behavior the and, or, nand, and not gates each compute the respective function of the inputs, and emit the result on the output the two-input truth table for the gates is the following. There are 5 basic gates used in performing logic operations in digital electronic namely buffer gate, not gate, and gate, or gate, xor gate each logic gate has a symbol for easy to identify , a mathematical expression to identify mathmatic logic operation and a truth table to completely describe operation of the.

A logic gate is an elementary building block of a digital circuit most logic gates have two inputs and one output at any given moment, every terminal is in one of the two binary conditions low (0) or high (1), represented by different voltage levels the logic state of a terminal can, and generally does, change. Now it is easy to see that $a+\overline{a}b=a+b$ , which can be checked from the truth table easily the resulting realization of or gate is shown in 1211 figure 1211: realization of or gate by nand gates \includegraphics[width=25 in]{lec15figs/11eps} and gate figure 1212: realization of and gate by nand gates.

An and gate is like a series circuit--if one input is off or one part of the circuit is broken, the output is off an or gate is like a parallel circuit--if at least one input is on or one path through the circuit is complete, the output is on this comparison can be particularly helpful if your class includes a number of other stem majors or. Or gates an or gate will give a high output if any of the inputs is high for example, in a simple lighting circuit with two switches in parallel the lamp will light if either switch is pressed. All digital systems can be constructed by only three basic logic gates these basic gates are called the and gate, the or gate, and the not gate some textbooks also include the nand gate, the nor gate and the eor gate as the members of the family of basic logic gates the description of the operations of these gates.

An or gate is a digital logic gate with two or more inputs and one output that performs logical disjunction the output of an or gate is true when one or more of its inputs are true if all of an or gate's inputs are false, then the output of the or gate is false the truth table for an or gate with two inputs appears to the right. The nand gate and the nor gate can be said to be universal gates since combinations of them can be used to accomplish any of the basic operations and can thus produce an inverter, an or gate or an and gate the non-inverting gates do not have this versatility since they can't produce an invert.

## And gate and or gate

I will explain, but first let me say to those who have been playing with this puzzle: (a) you can not use xor gates and (b) there really is a solution in fact, as the black adder would say (for those au fait with british comedy): this solution is so cunning that we could pin a tail on it and call it a weasel note: if you are a.

• The and gate is a basic digital logic gate that implements logical conjunction - it behaves according to the truth table to the right 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, a low output results the function can be extended to any number.
• Inverters and buffers exhaust the possibilities for single-input gate circuits what more can be done with a single logic signal but to buffer it or invert it to explore more logic gate possibilities, we must add more input terminals to the circuit(s) adding more input terminals to a logic gate increases the number of input state.
• Logic gates are available at mouser electronics mouser offers inventory, pricing, & datasheets for logic gates.

Digital electronics tutorial about the logic and gate and the logic and gate truth table used in digital ttl or cmos logic gate circuits. A logic gate can be thought of as a simple device that will return a number of outputs, determined by the pattern of inputs and rules that the logic gate follows for example, if both inputs in an and gate are in the 'true'/'on'/'powered'/'1' state, then the gate will return 'true'/'on'/'powered'/'1' there are many. A simple explanation of how electronic logic gates work, including and, or, not , and nor. 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 it is also common to use the '∧' symbol or simply “and” the hardware symbol for the and gate is shown in figure 41 the inputs are x and y the resulting output, x ⋅ y.
