Refer to the binary counter of Figure 5-48. Change it by connecting X0 to the CLK of flip-flop X1, and X1 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?

Latches and Flip Flop

Just like logic gates, the latches and flip-flops are the important elements of an electronic circuit. The logic gates form the important part of combinatorial circuits, while the latches and flip-flops form the essential part of a sequential circuit. Sequential circuits form the important concept of automata theory in electronics and electrical engineering, these circuits are a kind of logic circuit whose output depends on both present input and past inputs, that is, the input history.
