Number system | Digital Logic Design

 To count, to measure any thing number use.

example to measure height, weight, length 

In computer number system is important because if we talk about videos, images text computer understand 0,1 binary number system so conversion is important computer convert into binary number system.

so number system is important 

Most important number systems are:

• Binary number system

0,1

0,1 are 2 numbers so base/ radix is 2 AND range is (0,1) 

• octal number system

8 octal number system (0,1,2,3,4,5,6,7) and range is (0-7)

• decimal

10 decimal number system 10 is base/radix (0,1,2,3,4,5,6,7,8,9)

• hexadecimal

base is 16

hexadecimal number system base is (0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F)

because 10,11,12,13,14,15 are 2 2 symbol so use A,B,C,D,E,F

( )n n is base or radix if given any nth term to fine number system

we must remember (n-1) is base

e.g;- ( )12

n-1 

12-1=11

so we write in number system as

0,1,2,3,4,5,6,7,8,9,A,B

How to Convert Decimal number system:

Conversion of decimal number system

1. Decimal to Binary
2. Decimal to Octal
3. Decimal to HexaDecimal
