Study Notes
Number Systems in Digital Electronics
- Number systems represent information mathematically using specific bases or radices.
- Common number systems include decimal (base 10), binary (base 2), octal (base 8), and hexadecimal (base 16).
- The base of a number system indicates the total unique digits used, with digits ranging from 0 to (base - 1).
Definition and Importance
- A number system provides a structured method to represent numbers uniquely and facilitates arithmetic operations.
- Each digit’s value is influenced by its position, representing powers of the base.
- Applications span data storage, processing, communication, and hardware design.
Types of Number Systems
-
Decimal Number System:
- Base 10, utilizes digits 0-9.
- Each digit's value is a power of 10.
-
Binary Number System:
- Base 2, limited to digits 0 and 1.
- Central to digital devices for performing operations and data storage.
-
Octal Number System:
- Base 8, uses digits 0-7.
- Represents values using eight symbols.
-
Hexadecimal Number System:
- Base 16, includes digits 0-9 and letters A-F (where A=10, B=11, up to F=15).
- Commonly used in computing and digital electronics.
Conversion Methods
- Binary to Decimal: Multiply each binary digit by 2 raised to its positional power and sum the results.
- Decimal to Binary: Divide the decimal number by 2 and record remainders until reaching 0; read remainders in reverse for binary representation.
- Binary to Octal: Group binary digits into sets of three (from the right) and convert each group to octal.
- Octal to Binary: Convert each octal digit to its three-digit binary equivalent.
- Binary to Hexadecimal: Group binary digits into sets of four (from the right) and convert each group to hexadecimal.
- Hexadecimal to Binary: Convert each hexadecimal digit to its four-digit binary equivalent.
