Suppose that each component in the circuit below has a propagation delay (tpd) of 10ns, a contamination delay (tcd) of 1ns, and negligable rise and fall times. Suppose initially that all four inputs are 1 for a long time and then the input D changes to 0.
Draw a waveform plot showing how X, Y, Z, W and Q change with time after the input transition on D.
