Figure 5-33(a) shows the symbol for a J-K FF that responds to a NGT on its clock input and has active-LOW asynchronous inputs. The external active- LOW asynchronous inputs are labeled PRE and CLR. The bubble on an input means that the input responds to a logic LOW signal. The J and K inputs are shown tied HIGH for this example. Determine the Q output in response to the input waveforms shown in Figure 5-33(a). Assume that Q is initially HIGH.
