JK Flip Flop

We have seen the JK flip flop in use as memory for the pedx controller. We now look at its operation.

Create a new Xilinx schematic project called jkff-s, download the zip file jkff-s.zip and extract the schematic jkff-s1.sch into your main project folder jkff-s. Open the schematic and add to the project. Start the Logic Simulator.

Simulate the the JK flip flop:

1.

Set CE=1, S=R=0, and investigate the behaviour by completing the following table for the JK flip flop:

J	K	Qt+
0	0
0	1
1	0
1	1

2.

Include sketches or printouts of the waveforms in your notebooks.
