project it does notberkeman said:@NYAME EPHRAIM -- is this for a schoolwork question or schoolwork project?
it does not even simulate in the first pleaseCWatters said:I don't know if this is the problem as it depends on your simulator but...
If you built this circuit and powered it up what would the output state be? Q=1,0 or indeterminate?
it does not work when i simulate it, i don't know if the nand gates i used are the current gates or they are specifications ?CWatters said:Circuit looks ok to me. What do you mean by "does not simulate"?
well when you power it up the output should be zero, one you change the stat ot any J or K, then one of the outputs will be high, the you can use the clock pulse to change the output state, as you apply the pulse the output state change one side becoming high and the other low!NYAME EPHRAIM said:project it does not

What software are you using to simulate it? Does the software have a way you can label all of the node voltages? How do you define the 2 inputs at the left?NYAME EPHRAIM said:well when you power it up the output should be zero, one you change the stat ot any J or K, then one of the outputs will be high, the you can use the clock pulse to change the output state, as you apply the pulse the output state change one side becoming high and the other low!

Only if you want the "clear" and "set" inputs. As basic design the layout in post 1 should work. It https://www.electronics-tutorials.ws/sequential/seq_2.html, however.Svein said:A JK flip-flop is considerably more complex:

Probably because the OP's circuit doesn't have Set and Clear inputs. Either way, unless the simulator is told what the initial state is, it can't know. A question I asked in an interview: What is the output state of such a circuit. Answer: Don't care. Actually, don't KNOW. If the output can detonate a bomb, you very much do care. You don't care what the J & K inputs are until you clock it, and if the inputs cause it to toggle, you still don't know what the outputs are.Svein said:A JK flip-flop is considerably more complex:

That is because the schematic is a logic simulation only, not hardware.gary350 said:I see no battery or power supply? There are no other parts, capacitors, resistors, diodes?
Yes, and yet he just posted a new thread start in the schoolwork forums 30 minutes ago (which was deleted for several reasons). So it seems he may not be interested in this thread anymore for some reason...CWatters said:The OP hasn't answered previous questions or contributed to this thread for 6 days.
There could be several reasons why your circuit is not simulating. One common reason is that there may be a mistake in the circuit design or wiring. Check to make sure all connections are correct and the components are placed in the right locations.
First, check for any potential errors in the circuit design or wiring. If everything seems correct, try using different components or a different simulation software. You can also consult online resources or ask for help from other scientists or engineers.
There may be a problem with the logic of your circuit. Double check your circuit design and ensure that the input signals are being correctly interpreted by the NAND gate and the JK flip flop. Additionally, check for any potential timing issues that could be causing unexpected results.
You can verify the functionality of your circuit by comparing the simulation results to the expected truth table for a JK flip flop NAND gate circuit. If the results match, then your circuit is likely functioning correctly.
If you have exhausted all troubleshooting methods and your circuit is still not simulating correctly, it may be helpful to consult with a more experienced scientist or engineer. They may be able to spot any mistakes or offer alternative solutions.
