Logic decoder

Can u tell me what is it ??

It is just practical of logic functions and it is simple like on and off

Except that your connections between gates is all wrong. You do not connect the pins of a transistor across the two inputs of a logic gate as you have done. Where did you learn to connect devices in such a way? I have been watching your drawings carefully and I just had to say that most if not all of your circuits do not work. I don't have any desire to tromp on you at all. But I just hate to see a person go off on such a bad path, believing he is creating good circuitry. Perhaps you are purposefully trying to fool somebody. I don't know. If you are sincere, then someone has done you a terrible disservice, teaching you in this way. I'm sorry to be the bearer of bad news.

I dont study at all about this but ill trying to make these circuits and slowly i understand whats this and ill made circuit just for fun not intrested in this subject but i trying to make no one teach me about these and this all i get from my mind which is absolutely destructive and i just trying to molded in my way or nothing

And if u want to teach me then please !!

Firstly, I am not a good teacher, so I will not try. I do like to experiment, but I will not publish my experiments to the public until I feel I am very close to a functional circuit. Your published works, to a novice, come across as if they are exact and correctly functional. The worry is that your examples will teach novices an incorrect lesson. We all like to experiment and I would suggest that you consider keeping these circuits private, until close to accurate. In my humble opinion.

As much as it seems... I am not out to get you. Wouldn't you feel better knowing that your circuits are real and functional? I would encourage you to take your time. Watch the other creations and think it through. Ask for assistance from time to time. Start with small circuits that you know work. There is no shortcut to knowledge. Learn it carefully and accurately. You will be proud of yourself by doing it right. Generating nonsense circuits helps no one, least of all yourself. You can do it well, if you wish to. I will be proud as well. Please try, for your own benefit.

I truly wish you Good Luck!
