Digital circuits are classified into combinational and sequential circuits regardless of their application. In the previous chapters, we have been dealing with logical or combinational circuits. The output of these circuits solely depends on the inputs. Combinational circuits can deliver an output by just applying desirable inputs. These circuits draw their signal paths from left to right. The combinational circuits do not give or store any information related to the previous outputs. A collection of circuits whose output depends on the earlier behaviour of the circuit as well as the present values of the inputs are known as sequential circuits. They work on the feedback principle. Owing to the dependency on past conditions, the sequential ...
