Assume that Q starts LOW. 6. Sketch the Q output for the circuit shown below. Assume that Q starts LOW. 7. Sketch the Q output for the circuit shown below. Assume that Q starts LOW. 8. Sketch the Q output for the circuit shown below. Assume that Q starts LOW.9. Sketch the Q output for the circuit shown below. Assume that Q starts LOW. Note that the clock goes through a negative edge detection circuit. In your own words, explain the differences between a flip-flop’s asynchronous input and synchronous input. Be as clear and detailed as possible in your explanation.
