q output การใช้

• That captured value becomes the Q output.
• There is a single Q output that can be set with the SEQ instruction and reset with the REQ instruction.
• A'one-hot'implementation would have fifteen flip flops chained in series with the Q output of each flip flop connected to the D input of the next and the D input of the first flip flop connected to the Q output of the fifteenth flip flop.

• :Taking the first transition as an example, to make state 0001 change to 0010, the four JK inputs must make the four Q outputs do this : 0?! 0, 0?! 0, 0?! 1, 1?! 0 ( that's Qd, Qc, Qb, Qa, respectively ).
• While the R and S inputs are both low, feedback maintains the Q and outputs in a constant state, with the complement of Q . If S ( " Set " ) is pulsed high while R ( " Reset " ) is held low, then the Q output is forced high, and stays high when S returns to low; similarly, if R is pulsed high while S is held low, then the Q output is forced low, and stays low when R returns to low.
