OTHER MEANINGS
2. A circuit that performs subtraction using combinational logic rather than sequential logic.
Unlike a sequential subtractor, the combinational subtractor produces its result immediately from the inputs.
3. A hardware module that computes the difference of two binary operands.
The ALU includes a combinational subtractor for arithmetic operations.
4. A teaching model used to demonstrate binary subtraction with gates.
The lab manual describes a 4-bit combinational subtractor built from full subtractors.
