John: Now, see the 1st picture above. Which part is correct?

Me: Normally, the part of left hand side is correct. That mean, when the data input line is on Up cyle, Gate A and Gate B are on Up cycle.

John: You're wrong. The part of right hand side is correct too.

Me: That mean, when the data input line is on Up cycle, Gate A can be on Up cycle and Gate B can be on down cycle.

John: You're correct. OK. I intepret it in code.

If (Gate A = Up cyle)

{

Set = 1;

if (Gate B = Down cyle)

{

Inverter = true;

if (inverter = true)

{

Gate B = 1;

if (Gate B = 1)

{

Reset = 1;

If (Set = 1 & Reset = 1)

{

The circuit of the Flip Flop = Unstable.

}

}

}

}

}

John: Now, See 2nd picture above. Which part is correct?

Me: Normally, the part of left hand side is correct. That mean, when the clock line is on Up cycle, Gate A and Gate B are on Up cycle.

John: You're wrong. The part of right hand side is correct too. That mean, when the clock line is on Up cycle, Gate A can be on down cycle and Gate B can be on Up cycle.
