I have a small doubt... regarding some grammar in a question

conversion

What does the following mean?

"Design a conversion circuit to convert T flip flop to J-K Flip Flop."

Can someone provide me a rough solution to this??

I know all the state table stuff but i want to know what the question actually means... Please help...

regarding to grammar

purifier,
It means that you need to design a "front end" logic circuit to the "T" flip-flop that has 4 inputs, J, K, input clock, "T" flip flop output. The circuit will have 1 output; the clock output that goes to the clock input to the "T" flip flop. You need to design the circuit so that at an input clock transition, you will either provide a clock output pulse to the "T" flip-flop or not, depending on whether a change of state of the "T" flip flop is required in order to make it behave like a J-K flip-flop.
~
For example:
The "T" flip-flop is in the "1" state
J = 1, K = 0. The required next state of the "T" flip-flop is "1". The "T" flip-flop is already in the "1" state, so you would not provide a clock input to the "T" for this input state.

convert t flip-flop to jk flip-flop

Thank you very much. So does it mean that i'll have to design the circuit after getting J and K in terms of T, Qn and Qn'? Sorry if it is a silly doubt but its been bothering me for quite a while...

J K T Clkout Comment
0 0 0 0 This is the "No Change" state for the J-K FF, so no toggle
0 0 1 0 This is the "No Change" state for the J-K FF, so no toggle
0 1 0 0 This is the "0" state for JK, but T is already "0", no toggle
0 1 1 1 This is the "0" state for JK, but T is "1" so toggle it
1 0 0 1 This is the "1" state for JK, but "T" is 0 so toggle it
1 0 1 0 This is the "1' state for JK, but "T" is already 1, so no toggle
1 1 0 1 This is the "toggle" sate for JK, so toggle the "T"
1 1 1 1 This is the "toggle" sate for JK, so toggle the "T"

Notice that for the 1st 2 states, and the last 2 states the "T" state is a "Don't Care". This can be used to your advantage in simplifying the logic design of the "front-end".

you have to convert the circuit in t flip flop.
