Refer to the binary counter of Figure 5-48. Change it by connecting X̅₀ to the CLK of flip-flop X₁, and X̅₁ to the CLK of flip-flop X₂. Start with all FFs in the 1 state, and draw the various FF output waveforms (X₀, X₁, X₂,) for 16 input pulses. Then list the sequence of FF states as was done in Figure 5-49. This counter is called a down counter. Why?
