Ripple Counter: Wrong Trigger Stage Debug
A 3-bit asynchronous ripple counter divides the input clock frequency by cascading T flip-flops. Each stage after the first must trigger based on the output of the preceding stage to properly divide the frequency.
Expected behavior:
| CLK Pulses | Q2 | Q1 | Q0 | |--------------|------|------|------| | 0 | 0 | 0 | 0 | | 1 | 0 | 0 | 1 | | 2 | 0 | 1 | 0 | | 3 | 0 | 1 | 1 | | 4 | 1 | 0 | 0 | | 5 | 1 | 0 | 1 | | 6 | 1 | 1 | 0 | | 7 | 1 | 1 | 1 |
Simulation shows Q2 toggling on every clock edge, identical to Q0. After the first clock pulse, the output jumps incorrectly from 000 to 101 instead of 001. Inspect the circuit and correct the fault.
Constraints
- Do not add new logic gates or flip-flops to the circuit.
- Only modify the wiring of the existing components.
- Maintain the asynchronous ripple design: do not convert this to a synchronous counter.

Solve this problem
Place the gates, wire them up and watch the signals settle. Every submission runs on the same simulation engine that grades it.
