Questionii. Define all two subtractors types and design a full subtractor (3 mark)
QUESTION TWO SEQUENTIAL CIRCUIT (5 mark)
1. Give the difference between combinational circuit and sequential circuit (1 mark)

Studdy Solution
Differentiate between combinational and sequential circuits:
- **Combinational Circuit**: - Output depends only on the current inputs. - No memory elements; no feedback paths. - Examples include adders, subtractors, and multiplexers.
- **Sequential Circuit**: - Output depends on both current inputs and past inputs (history). - Contains memory elements like flip-flops or latches. - Examples include counters, shift registers, and memory units.
