Sequential logic circuits are used to construct finite state machines which are basic building block in all digital circuitry and also in memory circuits. State of sequential circuit at any given time. Sequential circuits are essentially combinational circuits with feedback.
State of sequential circuit at any given time.
The outputs of the sequential circuits depend on both the combination of present inputs and previous outputs. In this design the state assignment may be important because the use of a good state assignment can reduce the required number of product terms and hence reduce the required size of the pla. What are the different types of sequential logic circuits. Sequential circuits can be realized using plas programmable logic arrays and flip flops.
