Design of combinational circuits,nal design is an essential prerequisite to the design of more complex sequential systems. A . logic circuit has the characteristic that the steady-state output obtained from the circuit is dependent only upon the present state of the input. Therefore, if the input and output signals are denoted by .

Implementation of combinational circuits,rms represent AND/OR or OR/AND two-level circuits. In practice there are a large number of ways of implementing logic functions using commercially available components. These range from individual gates in the form of SSI components, through MSI components such as decoders and multiplexers, to semi-

GRAZE

Sequential circuits,actical systems we must consider another, more general, type of circuit, where the output is a function of both present and . inputs. These circuits, called . circuits (also known as . or .) are contained in most digital systems as counters, registers, memories, etc. A familiar example of sequential

Design of asynchronous circuits,l design techniques must be employed to overcome the problems brought about by the absence of any timing pulses, that is, the absence of a common clock signal. These problems arise mainly as a result of the finite switching time, or propagation delay, of the basic logic modules. In synchronous syste

贵族

Design of regular arrays,and constructing subsystems which can then be repeated or replicated to form the complete system. In the context of digital systems we have already seen several examples of the application of this principle, including both combinational and sequential circuits, for example, ripple-carry adders, casc
