Ok so I have an exam tomorrow in Digital Logic and I really need a bit of help. I'm looking through a few past exam papers, and I think if I get general solutions to the following questions then I should be ok:
1) What is the difference between a 4-bit binary integer and a 5-bit binary coded decimal (BCD) integer? The book doesn't seem to mention it. The example given in the question is:
Binary integer 1100 converts to the BCD integer 10010
2) I'll just give an example question:
3) I'll give another example question:
So yeah if I could get any help on any of the above examples I'd appreciate it a lot!!

2) I'll just give an example question:
Ok so I know how to convert a transition table into a primitive flow table... but I don't understand how you can get a transition table from the information given. I always thought that a transition table showed the change from one state to another..?IF (x = 1) AND (y = 0)THEN Q = 0ELSEIF (x = 1) AND (y = 1)
THEN Q = (Qlast)'......(the compliment of Qlast)ELSE
Q = (y)'ENDIF
(a) Derive the draft transition table
(b) Expand the draft transition table to form a total transition table
(c) Convert the total transition table into a primitive flow table
3) I'll give another example question:
Again, I think I'm just getting confused with transition tables here...A gated J-K latch is an asynchronous sequential logic circuit that is unstable when the J,K and G (gate) inputs are all at logic 1.(a) Derive the transition table and show that this is so, and
(b) How would you overcome this?
So yeah if I could get any help on any of the above examples I'd appreciate it a lot!!
