| Dec 9, 2021 at 17:49 | comment | added | Andy aka | @RasmusFriisKjeldsen - that's a bit of a show-stopper for simple circuits. I've now officially interpreted your new requirements and I have concluded that the answer to your question is no. If, you wish to ask a brand new question based on solving your new requirements, then please do so. You should be aware that I am advising this based on this site being a Q and A site with an allergic disposition to significantly changing goal-posts. It's also not in this site's interest (or mine) to become a forum-for (or participant-to) solving evolving problems or servicing progressive teaching studies. | |

| Dec 9, 2021 at 11:57 | comment | added | Andy aka | From your words, that is exactly what I construed you required. I think you need to be a lot clearer about what you want and, importantly, what you don't want to happen. | |
| Dec 9, 2021 at 11:53 | comment | added | Rasmus Friis Kjeldsen | If you look at the pulse, it has 2 negative parts and one positive part. My circuit will light up the led on the positive part, and your added circuit will light up the led on the negative part, so as both are present in the pulse, both leds light up. If the polarity of the pulse is reversed, both leds will still light up. | |
| Dec 9, 2021 at 11:46 | comment | added | Andy aka | @RasmusFriisKjeldsen how can that be so given you have diodes that protect against reverse polarity? I believe you may be misled. | |
| Dec 9, 2021 at 11:44 | comment | added | Rasmus Friis Kjeldsen | My initial circuit blinks no matter the polarity of the pulse, as the pulse has both a negative part and a positive part. Unfortunately it is not so simple as to just add the circuit you suggest. | |
