What can a logic circuit be used for?
Computers often chain logic gates together, by taking the output from one gate and using it as the input to another gate. We call that a logic circuit. Circuits enables computers to do more complex operations than they could accomplish with just a single gate.
What devices use logic gates?
Logic circuits include such devices as multiplexers, registers, arithmetic logic units (ALUs), 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 (metal–oxide–semiconductor field-effect transistors).
What are the five uses of logic gate?
Logic gates are used as building blocks of digital electronic hardware.
How does a logic gate in a microchip work?
“In a logic-gate arrangement, each of the MOSFETs works like a switch. The switch is closed, or the MOSFET is turned on, if electric current can flow readily from the source to the drain. The switch is open, or the MOSFET is turned off, if electric current cannot flow from the source to the drain.
How are logic gates implemented in a circuit?
Logic gates are implemented by using transistors, diodes, relays, optics and molecules or even by several mechanical elements. Due to this reason logic gates can also be considered as electronic circuits. The logic gates can be build up in a wide variety forms such as large-scale integrated circuits (LSI),…
How are the inputs and outputs of discrete Gates represented?
Discrete AND gates may be realized by using diodes or transistors. The inputs represented as X and Y may be either 0V or +5V correspondingly. The output is represented by Z .
Is the OR gate the same as the circuit?
Another type of logic gate is the OR gate. The circuit symbol is that arrowhead kind of shape, and inputs and outputs are marked the same way as the AND gate. Let’s look at the OR gate’s truth diagram. As you can see, as long as any one of the inputs is 1, the output will be 1 and only if all inputs are 0 will the result be 0.
