[LEARN] LOGIC GATES and chance to earn merit.

[Peanutswar]

As you can see there are a lot of people seeing the word NOT, AND, NAND, OR, NOR, XOR,and  XNOR most of the time in cryptography and some of them are listed into the different cypher, now I want to share how to use this logic gates that can use into your encryption and also use to the world of blockchain. Also you can check this out if you want to learn more

NOT Gate



NOT is just basically reversing the value/s of the given problem

A	|	X
0	|	1

Example :

A	|	X
11010101	|	01101010

OR GATE
When there is a true value (1) the answer becomes true

A	|	B	|	X
110	|	101	|	111	|

Example :

A	|	B	|	X
00110011	|	10011001	|	10111011

NOR GATE
When there is a true value (1) the answer becomes false

A	|	B	|	X
110	|	101	|	000	|

Example :

A	|	B	|	X
00110011	|	10011001	|	01000100

AND GATE
When there is a false value (0) the answer becomes false

A	|	B	|	X
011	|	110	|	010	|

Example :

A	|	B	|	X
10101100	|	10001100	|	10001100

NAND GATE
When there is a false value (0) the answer becomes true

A	|	B	|	X
011	|	110	|	101	|

Example :

A	|	B	|	X
10101100	|	10001100	|	01110011

XOR GATE
When there is a two same value  the answer becomes false.

A	|	B	|	X
011	|	110	|	101	|

Example :

A	|	B	|	X
10101100	|	10001100	|	00100000

XNOR GATE
When there is a two same value  the answer becomes true.

A	|	B	|	X
011	|	110	|	010	|

Example :

A	|	B	|	X
10101100	|	10001100	|	11010000

Now here is the challenge for the 10x newbies up to Jr. member you can earn one (1) merit if you answer all of this problem.




OR

A B	00011001 00011010

NOR

A B	10110011 01001100

XNOR

A B	10001101 11111111

To the people get curious how do I make those logic gates you can use this platform, there are a lot of use this too like making a diagram for data flow/data chart.

Have to comment that the OP reminds me of some of the content I studied back at university, although the context there was learning the underlying basis of computer designs (or something like that), being the diagrams a graphical representation of basic boolean processing operators (1’s and 0’s were really -5V, -5V under the hood back then).

[Maus0728]

This lecture reminds me of our lecture in basic logic circuit last year when I was still a freshman college student in computer engineering. Those "1" and "0" are basically equivalent to "TRUE" and "FALSE" in terms of truth table in discreet mathematics.

Here are some of the application using breadboard.

Once you have a mistake on your calculations to your logic circuit it will ruin all of your hard work, still with the help of the tinkercard exploding Intergrated circuit no more because it may help what are the parts do we need. I'm using logic dates on our discrete math and it gives a lot of lossing a lot of neurons because you need to do the simplified form.

Good to see that your 7 segment are still there, still that working?. To the people does not know the 7 segment it display a 7 LED.

This is one of the projects i made with the use of tinkercad.

[ryzaadit]

A bit harsh, f*ck off you reminds me about this shit mattery when i learning this shit on the "High School".

In the "High School" choose the study program "Audio-Video" when i thinking this study learning about editing, camera, and other things about the video. But the reality this study program learning about electronica and makes me a headache.

The reason, I don't math but choose the wrong study program when math was kind of important on this study program. Want to answer the question, but seem like only for Newbie - Jr.Member

It's actually a "seven segment double digit logic circuit" but it happens that the other seven segment digit has malfunctioned. I've used IC 192, IC 47 and 555 timer.

This is one of the projects i made with the use of tinkercad.

Nice! Thanks for sharing this virtual tool. Our professor did not told us that there is an existing tool to create a virtual circuit that can be used as a diagram to follow when doing the actual circuit.

A bit harsh, f*ck off you reminds me about this shit mattery when i learning this shit on the "High School".

It looks like you are having a bad time with the use of the logic circuit that's alright because I feel the same, in our subject when the discrete math my professor gives a lot of problem like the OP given to the newbies a chance to earn merit. Also forgot the thing called as the AND only will use and convert into one integrated circuit only. But still, this is a good thing to learn with those I also checked the link by the google patents and there are related to the use of the logic gates.

I think OP will be allowed you to answer this because it helps to your skills too but the objective of the OP is to help members to earn merit too. I would like to ask too that we need to provide the solution too?, I want to answer this to try if I still remember all of the lessons we have before.

I'm neither a newbie or jr member but I just want to participate in the challenge for the fun of it. My knowledge about logic gates have become a little rusty since the lockdown but here goes:

1.   11001101
2.   00100111
3.   00000010
4. 1 (NOT 0 is 1)
5. 1 (true: 1 OR 1 = true/1)

Not sure about my answers but It'd be nice to know if I did get them right.

This logic and Boolean gate theory had been a tough class for me back in those day in high school, seeing those diagrams and charts makes me have a feeling that what you gave learnt before still comes to future in different dimension, I would have joined the challenge but have no idea about it. Success for those that hit it right.

This is so far the most easy and basic topic that needs to be mastered in order to understand the underlying logic behind these logic circuit. Try to study the "Truth Table", it'll give you the basic idea why the output is changing when the operator differs at some point.

I've also found a good research what is the connection of Logic Gates in terms of blockchain.

i think it would be better if these operations are referred to as bitwise operations since that is what they are called in programming and cryptography.
additionally there are only 4 main operations: AND(&), OR(|), XOR(^), NOT (~ or unary operation). others such as XNOR are the combination of these operations:

Code:

NAND=NOT(AND) -> ~(A & B)
NOR =NOT(OR)  -> ~(A | B)
XNOR=NOT(XOR) -> ~(A ^ B)

The reason that I passed my subject into the discrete mathematics is because of this truth table I highly prefer that you must need to be aware the things you are doing especially computing the values of 0s and 1s because once you make a mistake on it there is a chance you will make an error or mistake on your breadboard that causes to your integrated circuit(IC) to explode most and I remember that I exploded almost four (4) IC because not having a good attention to my computation before.

Code:

NAND=NOT(AND) -> ~(A & B)
NOR =NOT(OR)  -> ~(A | B)
XNOR=NOT(XOR) -> ~(A ^ B)

I will update this as soon as possble to make an addition with this bitwise operation, also the if and then statement to make more understanding about these too.

This reminds me of my brother working hard just to make it work. I haven't had a lesson like this back in my high school days and even in college still didn't have classess like this about electronics since the course I take is not about electronics. I'll try to study a bit about that and i'll try to answer just for fun or challenge.

[Blank-Head]

OP really described well and thanks for this great lesson.
I think if you add Truth Table with your logic gate then it will be more simple to learn.

Here are some Logic Gates with truth table.

I remembered our project last year. The hard thing here is all the wires because it makes you confused whether you put it to the right place or not.

It's obvious how much most persons learn and forget what we've learnt!
You know, I recall this from my days in high school while taking some computer lessons. It's always so easy to interpret but I barely get the hang of it now. I guess I'll try a review if it much later.
Hope you guys do too. Don't just let it be a familiar, know it.

[Wolfencloud]

These logic gates reminds of what I used to learn during a lecture form my subject and for sure I always enjoyed this logic gates because it catches my interest. But as of now, I am not really that interested on solving problems with the use of those logic gates, but this topic is a very interesting topic especially for those people who uses breadboard and some circuits.
