Question

Difference between the combinational circuit and flip flop

Answer 1

Answer:

Combinational circuits are defined as the time independent circuits which do not depends upon previous inputs to generate any output are termed as combinational circuits. Sequential circuits are those which are dependent on clock cycles and depends on present as well as past inputs to generate any output.

Combinational Circuit –

1. In this output depends only upon present input.

2. Speed is fast.

3. It is designed easy.

4. There is no feedback between input and output.

5. This is time independent.

6. Elementary building blocks: Logic gates

7. Used for arithmetic as well as boolean operations.

8. Combinational circuits don’t have capability to store any state.

9. As combinational circuits don’t have clock, they don’t require triggering.

10. These circuits do not have any memory element.

11. It is easy to use and handle.

Examples – Encoder, Decoder, Multiplexer, Demultiplexer

Sequential Circuit -

1. In this output depends upon present as well as past input.

2 Speed is slow.

3. It is designed tough as compared to 4. combinational circuits.

4. There exists a feedback path between input and output.

5. This is time dependent.

6. Elementary building blocks: Flip-flops

7. Mainly used for storing data.

8. Sequential circuits have capability to store any state or to retain earlier state.

9. As sequential circuits are clock dependent they need triggering.

10. These circuits have memory element.

11. It is not easy to use and handle.

Examples – Flip-flops, Counters

Answer 2

The differences between the integrated circuit and the flip flop are:

• The sensible circuit included is the output depending on its current input.
• Consecutive circuits, on the other hand, are constructed using a combined circuit and memory elements called flip-flops.
• These circuits produce output based on current and previous conditions.
• In the first method, throw two latches in such a way that the first latch is opened for all the positive clock strikes and the second dial is enabled for all negative clocks.
• For the combination of these two latches to be flip-flop.
• In the second method, we can directly use the flip-flop, which is sensitive to the edges.
