Help building one flip flop using another? (Digital Logic Design)

[Chandasouk]

Can anyone show me the proper procedure to construct a flip flop using another flip flop? My Teaching Assistant gave us these steps you can use on any occasion but I cannot seem to apply it in this certain case.

How do you build a JK flip flop using a Toggle Flip Flop with an Enable?

The steps my Teaching Assistant said was to

first construct a Transition Diagram (For the JK flip flop)
Write down the Excitation Table for the Toggle
construct a State Table
make a K-map so you know what gates to connect with what inputs

I am stuck at how to make the state table. Can someone show me what it would look like?

I need to learn this before my exam Tuesday...

Here is an example of what the state table for the JK flip flop might look like using a Toggle Flip Flop with an Enable:State \ JK | 0 0 | 0 1 | 1 0 | 1 1 ---------|----|-----|-----|-----Q(n-1) | Q | Q' | Q | Q'Toggle | 0 | 1 | 1 | 0Enable | 0 | 0 | 1 | 1
