What is difference between logic AND gate?
Both AND logic gate and OR logic gate are the two basic logic gates used in digital circuits. The crucial difference between AND gate and OR gate is that AND gate performs multiplication of the digital inputs. As against the OR logic gate is used to execute the addition of the digital inputs.
Are cpus just logic gates?
TL; DR: Processors are made of logic gates and they have to be! If you are talking about actual chips installed on a circuit board, read on. The PDP-11 processor is actually made mostly out of 7400-series TTL logic.
Are transistors the same as logic gates?
“A logic gate in a microchip is made up of a specific arrangement of transistors. For modern microchips, the transistors are of the kind called Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET), and the semiconductor used is silicon. “In a logic-gate arrangement, each of the MOSFETs works like a switch.
Is a transistor a gate?
So yes, you have an AND gate where an input is fixed to 1. As mentioned elsewhere in the answers, you would need resistors to polarize the transistor and when applying a “1” to the base, you would then see the collector voltage drop toward zero. Your singled out transistor is an NAND gate acting as an inverter buffer.
What are the logic gates in digital system?
Digital systems are said to be constructed by using logic gates. These gates are the AND, OR, NOT, NAND, NOR, EXOR and EXNOR gates. The basic operations are described below with the aid of truth tables.
What are LogLogic gates?
Logic gates are the basic building blocks of any digital system. It is an electronic circuit having one or more than one input and only one output. The relationship between the input and the output is based on a certain logic.
What is the difference between IC and logic gate?
Logic gates make up integrated circuits, and ICs make up electronic systems. Intel’s first claim to fame lay in its high-level integration of all the processor’s logic gates into a single complex processor chip – the Intel 4004 – released in late 1971. This was 4-bit microprocessor, intended for use in a calculator.
What is the combination of and and NOT gates?
The three gates (OR, AND and NOT), when connected in various combinations, give us basic logic gates such as NAND, NOR gates, which are the universal building blocks of digital circuits. This basic logic gate is the combination of AND and NOT gate.
