The circuit in Figure 5-86 can be used to generate two nonoverlapping clock signals at the same frequency. These clock signals were used in early microprocessor systems that required four different clock transitions to synchronize their operations.
(a) Draw the CP1 and CP2 timing waveforms if CLOCK is a 1-MHz square wave. Assume that tPLH and tPHL are 20 ns for the FF and 10 ns for the AND gates.

(b) This circuit would have a problem if the FF were changed to one that responds to a PGT at CLK. Draw the CP1 and CP2 waveforms for that situation. Pay particular attention to conditions that can produce glitches.
