Iam yet to make it neat by using comparators,counters to make it simple.I will re-organise the ones i get what is expected

If you give me a rough idea on how to go about it i will be greatful

 

Iam yet to make it neat by using comparators,counters to make it simple.

What you have already drawn is not neat. Neatness will allow you and others to follow the circuit more easily.

 

How do your labels correspond to the problem text? You have V0, V1, and V2. The problem says you have V1, V2, and V3.

Its just a labling error,thanks for alerting me.Otherwise the output should be alright

You need to slow down. Why are you quoting your own posts?

Check again.

I don't know what logic you're trying to implement, but the circled gates look suspicious to me.

Okay basically its a general 3 to 8 decoder.Why do you feel there is some problem here?

@Dennis could you please suggest the way you would have solved this task?.

The inputs are three c1,c2,c3 and A1,A2,A3.The decoder above will handle the speed between 0 to 7 as the output thats why i have 8 gates

If your work wasn't so sloppy, you could see that you haven't drawn it correctly. Two gates are V0V1, two gates are V0V1V2, and one gate only has one input connected.

Homework help doesn't work that way. We can offer guidance, but you have to do most of the work.

There's more than one way to solve this problem. Clearly your instructor has a method in mind. You need to show us what you've been studying so we can see what your instructor expects.

He didnt specify the method.If at all you give me the idea you have i will work on the easiest method.thats my truth table.

 

thats my truth table.

I assume you're doing this on a computer. Why are you taking distorted pictures of your screen and desk/keyboard? You can take screen captures or print to PDF.

This makes no sense. If V=0, why are you showing V1, V2, V3 in the table? By definition, they're all 0's.

Is this the method that you're being taught? It would be helpful if you posted your lecture notes on decoders.

EDIT: Your tables would be easier to read if you reduced the column width:


You're probably doing what your instructor is doing. S/he doesn't get it either. Having unnecessarily wide columns isn't helpful.

EDIT 2,3: Corrected table again; now matches OP's.

This part of the truth table is just a part showing whether the accelaration is successfull or unsuccessful.

The posted table is for V=0, why do you bother to show columns for V1, V2, and V3? They're all 0's. Showing irrelevant information isn't helpful.

 

Could you please guide me on what you have.I need the way to go so that i can work it out

The calculations of this table is not part of the markings.It is used to calculate the rules on the main document

dl324 and Dennis what do you have for me about these task?

Nothing until you provide the information I've asked for.

I'd be inclined to solve it using a Kmap with 6 variables. I doubt that your instructor has that in mind because you and he keep mentioning decoders. Besides, not many students could simplify a Kmap with 6 variables.

yea it needs to be a circuit.Thanks though

 

it needs to be a circuit.

This is what I meant:


It would have been twice the number of gates with your 2 input limitation, but doable. You just need to be able to solve a 6 variable Kmap.
