​The ‘memory’ of previous outputs in an asynchronous sequential circuit is provided by direct feedback from the internal output(s), Y, to the internal input(s), y, of the combinational logic block. Th...

For an asynchronous circuit to be of use it must have more than one external input (otherwise all the circuit has to respond to is a signal alternately changing its value from 0 to 1 to and so on). If...

Two-level circuits are direct implementations of sum of products and product of sums forms, either in fundamental form(straight from the truth table) or after minimisation. We now consider the advanta...

The idea of positive and negative assertion level logic arises directly out of duality. It is again based upon the fact that because Boolean algebra describes a two-state system then specifying the in...
