Questions and Answers

What is the main difference between sequential logic and combinational logic?

  • Combinational logic depends on the present and past inputs, while sequential logic depends only on the present input.
  • Sequential logic has no memory, while combinational logic has memory.
  • Combinational logic uses finite-state machines, while sequential logic does not.
  • Sequential logic depends on the present and past inputs, while combinational logic depends only on the present input. (correct)
  • What is the function of sequential logic in digital circuitry?

  • To generate random output
  • To process input signals without any memory
  • To construct finite-state machines (correct)
  • To perform complex mathematical operations
  • How are combinational and sequential logic used in practical digital devices?

  • Practical digital devices use sequential logic for memory and combinational logic for processing
  • Practical digital devices use only combinational logic
  • Practical digital devices use only sequential logic
  • Practical digital devices use a mixture of combinational and sequential logic (correct)
