| Aug 11 at 15:26 | comment | added | Francesco M. | I know that there are many sophisticated tricks, in the case of CMOS logic circuits, to obtain the same thing in a very short time, but the principle is the one we find in all digital electronics texts such as the one I mentioned previously, and which, among others, I taught for decades until 2011 using Floyd's text and not only. | |
| Aug 11 at 14:31 | comment | added | Neil_UK | @Franc As an exercise for you, consider what extra timing restriction and specification would be needed if normal edge-triggered storage latches were implemented using your suggestion. Now compare that with the timing of the actual master-slave latch implementation. | |
| Aug 11 at 14:16 | comment | added | santhoshkumar | can someone explain what is the difference between transition detectors and edge detector? because the combination circuit given by franc also able to detect edges, right? | |
| Aug 11 at 13:08 | comment | added | Neil_UK | @Franc If the question was 'how can you make an edge-triggered latch that's different to the way it's done at the moment in all D-type flip flops?', then your answer would be correct. However, the implied question is 'how do all the D-type flip-flops implemented in everything today work?' | |
| Aug 11 at 13:06 | comment | added | Justme | @Franc No they aren't talking nonsense. You have a valid edge detecting circuit. But flipflops don't use that kind of edge detector in their operation. If you think that's how flipflops detect edges, you need to show a reference which implements a flipflop with your edge detector. | |

Obfuscating your answer with lots of diagrams doesn't help any. Note that the site rules say that any posted diagrams should have their source cited. It might be tidiest to simply delete your answer. | |

| Aug 11 at 6:41 | comment | added | Francesco M. | The question is: "how flipflops can detect edges of the signal?" | |
| Aug 11 at 6:32 | comment | added | Neil_UK | He asked about flip-flops, not transition detectors. Look up flip-flops before you answer. | |
