Make logic circuit that do this:
inout | output
0 | 0
1 | 0

 

The solution has got to be the world's simplest circuit and it doesn't even need power to operate.

How to make it if must have power.
Or tell me how to make ALU from this video:https://www.coursera.org/learn/build-a-computer/lecture/6ZS46/unit-2-4-arithmetic-logic-unit

And not a single wire.

Welcome to AAC!

Or tell me how to make ALU

Sorry, but if you haven't solved the post #1 problem yourself your chances of successfully building an ALU range from infinitesimal to zero. You first need to do a lot of reading up about logic circuits. There are plenty of tutorials online.

If you want to build this particular ALU, it would take much understanding of how basic logic works.

You can actually buy a ready made 4 bit-ALU with 16 functions (4 bit function code) 74181 from the TTL family.

Your question is not clear. You have not indicated which are the input conditions and which are the output states.

Please post a schematic of your design and we will give you suggestions.

Make logic circuit that do this:

There are four possible logic functions with a single input.
Can you think of all four functions?

#1
input | output
0 |
1 |

#2
input | output
0 |
1 |

#3
input | output
0 |
1 |

#4
input | output
0 |
1 |

How would you implement in hardware each of the four functions?

 

I realyzed how to make this.
Sorry for this stupid question. XD

How many if "Hi-Z" is considered an output state? (Tri-state output with the output "off").

 

I believe this is an example of a fundamental gate type known and the "don't" gate, since it don't do nuthin'.

You didn't answer the questions I posed in post #9.

 

You didn't answer the questions I posed in post #9.

 

A AND (NOT A) = 0

Correct. In theory, yes.
In real life, FAIL. There is a problem with that circuit. Can you find the problem?

You are thinking too hard about this.
How else can you generate a 0 logic output?

I dont know.

 

I dont know.

What level are you at in basic digital logic design?

 

What level are you at in basic digital logic design?

I got there

 

I did not learn logic design just digital electronic.

 

I have no idea what this has to do with my question. I did not look at the video.

My question is, as expanded, are you in school?
What level school are you in, high school, college, university?
How many years schooling do you have?
Is this a course in digital circuit design? If so, how many lectures have you attended so far?
