Study Notes
Number Systems Overview
- A number system represents numbers or symbols systematically.
- The base or radix indicates the total number of symbols in a number system.
- Two main types of number systems are positional number systems and non-positional number systems.
Common Number Systems
-
Binary Number System:
- Base: 2
- Symbols: 0, 1
- Example: 10010
-
Decimal Number System:
- Base: 10
- Symbols: 0-9
- Example: 8910410
-
Octal Number System:
- Base: 8
- Symbols: 0-7
- Example: 176028
-
Hexadecimal Number System:
- Base: 16
- Symbols: 0-9, A-F
- Example: 8A6D16
Importance of Binary System
- Core to electronic circuit design, as digital circuits exclusively use binary digits (0, 1).
- Each binary digit (bit) represents successive powers of 2.
Binary Representation
- Positional values of a binary number:
- From right to left: 2^0 (1), 2^1 (2), 2^2 (4), 2^3 (8), 2^4 (16), 2^5 (32), ...
- A 4-bit binary number can represent 16 values (0 to 15).
- A 6-bit binary number can represent 64 values (0 to 63).
- A 16-bit binary number can represent 65536 values (0 to 65535).
Binary Arithmetic
- Basic operations: addition, subtraction, multiplication, and division.
Binary Addition
- Rules:
- 0 + 0 = 0
- 0 + 1 = 1
- 1 + 0 = 1
- 1 + 1 = 10 (carries over)
- Notable examples:
- 1001₂ + 1011₂ = 10100₂
- 101.101₂ + 111.11₂ = 1101.011₂
- 101101₂ + 101111₂ = 1011100₂
Binary Subtraction
- Rules:
- 0 - 0 = 0
- 1 - 1 = 0
- 1 - 0 = 1
- 0 - 1 = 1 (with borrow)
- Notable examples:
- 110₂ - 101₂ = 001₂
- 101101₂ - 1111₂ = 11110₂
- 110.01₂ - 101.11₂ = 000.10₂
- 11110₂ - 11101₂ = 00001₂
Verification of Operations
- Results from binary addition and subtraction can be verified by reversed operations.
Memory Units
- Binary representation is foundational for data storage and memory in computing.
