ok then how can we display letters separately on different 7 segment display?

If you had six displays you would need six decoders.
Or you can use one decoder and do TDM (time division multiplexing) where each display is enabled for one sixth of the total cycle.

As I commented before, the assignment as given is an unreasonable one for a class just starting off in digital logic.

can you tell which decoder ic we will use to display alphabets?
Thanks

That is part of the assignment. There is no decoder IC available. You have to create this yourself.
That is the purpose of the truth table. You don't need a table for all 26 letters of the alphabet. You only need a table for the letters in your name "KAMILAH".

Is this truth table right?

It is not about whether the table is right or wrong. It is about understanding the principles involved. I am not going to check your work for correctness.

Now, for the letters "KAMILAH", how many states are required to display all letters?

7 states are required to display all letters.

 

7 states are required to display all letters.

Ok. So now you need to add another column on the left side of the table to indicate the 7 states.

Ok i have added it.

 

Since you are likely going to be using a binary counter, start the first state at 0.

ok what to do next

 

ok what to do next

We have to consider the requirements of the assignment. Is there only one display or are there seven displays?
The solution is completely different for one, six, and seven displays.

Six displays

 

Six displays

Go back and talk to your professor. Your name is 7 characters and a 3 second delay between letters doesn't make sense if you have multiple displays. One of you doesn't understand the problem. My money is on the professor because it's his/her problem...

Your letters look strange to me:

 

Explain to your professor that you cannot show "K" and "M" on 7-segment displays.
Ask permission to use another name, such as "ELAYA".

Ok,we can do that.

I used the chart that @bertus posted.

Are you saying that you only have to spell out YOUR name and not any other name?

Also, what do you mean by "mux" and "demux" ?
