3bit jk synchronous counter. it counts till 5 then resets if oyuwant to remove the reset just disconnect the async reset .

This is a 2-bit counter. 2-bit counters normally can count 4 numbers: 0, 1, 2, 3. However, this circuit counts up to 2 and resets at 3. This can be scaled by adding more D flip-flops and setting the And gate at the location you want the count to stop at. You can also set a starting number in a similar fashion. This can be modified to a synchronous 2-bit counter using JK flip flops.
3 bit counter
A 2-bit counter that counts from 0 to 3! :D
Set "Count" to 1 to start counting and set it to 0 to pause the counter. Set "Increment/Decrement" to 1 to count up and 0 to count down.
4 bit Asynchronous Counter using JK FlipFlops
it counts.
it counts
it does what it says on the tin.
edit: the 13 is broken, but when I go in to edit everything breaks so :\ I'm pretty sure it's because I hooked up the 13 to the bottom left node in the "decoder4display"
edit: I went in to check and that is in fact the issue. I still have no clue wtf is wrong with the "decoder p1", as I changed literally nothing, but apparently I messed up. someone, please take a look at it and see what went wrong bc I really don't have any idea.
A completely original (4-bit) counter I made.
My first experiment with Subcircuits.
In this MOD 11 counter, it counts 0 to 10. i.e from 0000 to 1010, then it repeats itself. For 4 bits, 4 counters are required. Here -ve edge triggered T flipflop is taken.
TA = QA + QB.QC.QD; TB = QC.QD; TC = QD; TD = QA'
4-bit synchronous counter created using JK flip flops where mode, M=0 is the up counter and M=1 is the down counter.
A multiplication circuit designed to multiply two 8-bit numbers, creating a 16-bit output. The values are unsigned, and input into two locations in a currently unconventional way. The output is stored in the flip-flop array to the right. The button at the top starts or resets the program.
