familiar Gates Lesson Objectives: In addition to AND, OR, and NOT render, former(a) system of logic render like NAND and NOR argon also utilise in the design of digital circuits. The NOT circuit inverts the logic sense impression of a binary signal. The small slew ( riffle) at the production of the pictorial imageisation of a NOT door is formally called a negation indicator and designates the logical support. The objectives of this lesson ar to hear roughly: 1. Universal entrys - NAND and NOR. 2. How to implement NOT, AND, and OR ingress hand NAND supply only. 3. How to implement NOT, AND, and OR portal using NOR furnish only. 4. Equivalent entrys. 5. Two-level digital circuit implementations using universal supply only. 6. Two-level digital circuit implementations using other gates. NAND Gate: The NAND gate represents the complement of the AND operation. Its name is an abbreviation of NOT AND. The graphic symbol for the NAND gate consists of an AND symbol with a bubble on the production, denoting that a complement operation is performed on the output of the AND gate. The impartiality collar over and the graphic symbol of NAND gate is shown in the figure. The truth evade clearly shows that the NAND operation is the complement of the AND. NOR Gate: The NOR gate represents the complement of the OR operation. Its name is an abbreviation of NOT OR.

The graphic symbol for the NOR gate consists of an OR symbol with a bubble on the output, denoting that a complement operation is performed on the output of the OR gate. The truth table and the graphic symbol of NOR gate is shown in the figure. The truth table clearly s! hows that the NOR operation is the complement of the OR. Universal Gates: A universal gate is a gate which can implement any Boolean guide without deficiency to use any other gate type. The NAND and NOR gates are universal gates. In practice, this is advantageous since NAND and NOR gates are frugal and easier to fabricate and are the basic gates use in all IC digital logic families. In fact, an AND...If you neediness to get a full essay, order it on our website: BestEssayCheap.com
