Sequential Circuit A combinational circuit and storage elements are interconnected to form a sequential circuit. The storage elements are circuits that are capable of storing binary information. The binary information stored in these elements at any given time defines the state of the sequential circuit at that time. The sequential circuit receives binary information from its environment via inputs. These inputs together with the present state of the storage elements, determine the binary value of the outputs. They also determine the values used to specify the next state of the storage elements. The next state of the storage elements is also a function of the inputs and present state. Thus, a sequential circuit is specified by a time sequence of inputs, internal states, and outputs. Sequential Circuit Design A synchronous sequential circuit is made up of flipflops and combinational gates. The design of the circuit consists of choosing the flipflops and finding a combinational circuit structure which, together with the flip flops, produces a circuit that fulfills the stated specifications. The number of flipflops is determined from the number of states in the circuit; n flipflops can represent up to 2^n binary states. The combinational circuit is derived from the state table by evaluating the flipflop input equations and output equations. In fact, once the type and number of flipflops are determined, the design process involves a transformation from a sequential circuit problem into a combinational circuit problem. In this way, the techniques of combinational circuit design can be applied. Design Procedure Article Source: http://EzineArticles.com/?expert=Muhammad_Wasiq_Ansari
