Field programmable loglc
So far we have seen two extremes in the design options available to a digital designer-namely standard products and mask programmable ASICs....

Asynchronous and synchronous counters
To divide the counters we will look at into two types: asynchronous and synchro- nous. When used with respect to counters' these adjectives describe whether the Alip-flops holding the states of the ci...More -

Introduction to asynchronous sequential circuits
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...More -

Asynchronous circuit Inputs and race conditions
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...More -

Two-level circuits
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...More -

Positive and negative assertion level logic
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...More -
