Study Notes
Logic Gates & Numbering
- Logic gates are the fundamental building blocks of digital circuits.
- They perform logical operations.
- Each gate has one or more input signals and produces an output signal based on a specific logic.
- Basic logic gates include AND, OR, and NOT gates.
Basic Logic Gates
- AND gate: The output is 1 only if both inputs are 1. Otherwise, the output is 0. Z = A.B
- OR gate: The output is 1 if either input or both inputs are 1. Otherwise, the output is 0. Z = A + B.
- NOT gate: The output is the opposite of the input. If the input is 1, the output is 0. If the input is 0, the output is 1. Z = A.
Derived Logic Gates
- NAND gate
- NOR gate
- XOR gate
- XNOR gate
Numbering Systems
- There are multiple numbering systems used for different reasons, including:
- Decimal
- Binary
- Octal
- Hexadecimal
Decimal Numbering
- The decimal system uses the digits 0-9.
- It's also known as BASE 10.
Binary Numbering
- The binary system uses only the digits 0 and 1.
- It's also known as BASE 2.
Octal Numbering
- The octal system uses the digits 0-7.
- It's also known as BASE 8.
Hexadecimal Numbering
- The hexadecimal system uses the digits 0-9 and letters A-F.
- It's also known as BASE 16.
Conversions Between Numbering Systems
- Being able to convert between these systems is essential.
- Methods for converting between decimal and binary include the remainder method and the weights method.
Decimal to Binary Conversion (Remainder Method)
- Divide the decimal number repeatedly by 2 until you reach 0.
- The remainders, written in reverse order, are the binary equivalent.
Decimal to Binary Conversion (Weights Method)
- Determine the weights for each corresponding binary place value.
- Determine which weights add up to the decimal number.
- Place a 1 in those positions, and 0s elsewhere.
Binary to Decimal
- Each digit in the binary number corresponds to a power of 2.
- Multiply each digit by the corresponding power of 2 and add these products to get the decimal value.
Binary to Hexadecimal
- Group the binary digits into sets of four.
- Convert each group of four binary digits into its hexadecimal equivalent using the corresponding values.
Octal to Hexadecimal conversion (and vice versa)
- These conversions require intermediary steps in binary to achieve
