Study Notes
Digital Circuit Components
- Binary Decoder: Retrieves original data from encoded binary format, allowing the CPU to understand and execute instructions.
- Encoder: Converts data into a compact binary format, reducing the amount of data required for transmission or storage.
- Multiplexer: Selects and routes data from multiple input sources to a single output line, enabling efficient data transmission and processing.
- ALU (Arithmetic Logic Unit): Performs arithmetic and logical operations, such as addition, subtraction, AND, OR, and NOT, on data, facilitating execution of instructions and calculations.
- Full-Adder: A digital circuit that adds three binary digits (two operands and a carry-in) and produces a sum and a carry-out, enabling the calculation of binary arithmetic operations.
