Digital Principles and System Design - Boolean Algebra and Logic Gates - Glossary Technical Terms: Boolean Algebra and Logic Gates

GLOSSARY TERMS

1.     BCD- Binary Coded Decimal- Ways to encode the first 10 symbols of the decimal number system.

2.     Excess-3 code- Excess-3 is a non weighted code used to express decimal numbers. The code derives its name from the fact that each binary code is the corresponding 8421 code plus 0011(3).

3.     Gray code- Unit-Distance Codes- Only one bit changes between successive values.

4.     Boolean algebra- Boolean algebra is an algebraic structure defined by a set of elements B, together with two binary operators. ‘+’-‘and. ‘

5.     Minterm -A minterm is the product of N distinct literals where each literal occurs exactly once.

6.     Maxterm-A maxterm is the sum of N distinct literals where each literal occurs exactly once.

7.     Logic gate- Logic gates are the basic elements that make up a digital system. The electronic gate is a circuit that is able to operate on a number of binary inputs in order to perform a particular logical function.

8.     Universal gates -Universal gates are the ones which can be used for implementing any gate like AND, OR and NOT, or any combination of these basic gates; NAND and NOR gates are universal gates.

9.     Kamaugh map- K-maps are the convenient tool for representing switching functions of up to six variables. An n-variable K-map has 2n cells with each cell corresponding to a row of an n-variable truth.

10.            1’s complement-The 1’s complement of a binary number is the number that results when we all 1’s to zeros and the zeros to ones.
