Comparison should include
- combinational logic—involves decision making, using combinations of binary logic gates (e.g., (X + Y) + Z’ = A) in which output is always the same, depending on the input (0 or 1)
- sequential logic—involves timing and memory circuits, typically used for counters and shift registers, in which output varies.
Process/Skill Questions:
- How might a combinational logic circuit be used?
- How might a sequential logic circuit be used?
- What is a flip-flop?
- What is the relationship between a combinational logic diagram and its set of input?
