In the circuit below, the delay through each gate is 10 ns. Given the input signal A, sketch the signals B, C, and D. In the timing diagram, the width between each vertical dotted line is 100 ns as shown. If you are off slightly, it's okay. Don't worry about being super exact. But your sketch should indicate the basic operation of the circuit.
