Introduction In digital logic design, circuits fall into two categories: combinational logic and sequential logic . Combinational logic circuits are implementation of Booleanfunctions. They compute their outputs as functions of theirinput . They do not have any memory elements. Sequential logic circuits, implement functions with state .That is, they keep information internally (think of this informationbeing stored in data members of an object). The output of a sequentialcircuit depends not only on the input bits, but also on the internalstate. It turns out, for sequential circuits, it’s easier to designwith a clock. So, what’s a clock? Most people think of a clock as a way to tell time. Why woulda computer need to know how to tell time? A clock, on a computer, isn’t the same kind of clock usedin your home, or on a watch. If you’ve ever bought a computer,one of the more important features it the clock rate. For example,you may buy a machine that’s running at 2 GHz. Do you knoww...
