Sequential Logic System. These pulses are used to sequence the actions of other devices in the sequential logic circuit so that all the actions taking place in the circuit are properly synchronised. These sequential circuits deliver the output based on both the current and previously stored input variables.
What are sequential logic circuits. Combinational circuit produces an output based on input variable only but sequential circuit produces an output based on current input and previous input variables. These pulses are used to sequence the actions of other devices in the sequential logic circuit so that all the actions taking place in the circuit are properly synchronised.
Hence a sequential circuit s output depends on the current input as well as past input.
With the applied inputs to the combinational logic the circuit outputs are derived. The derived output is passed on to the next clock cycle. In automata theory sequential logic is a type of logic circuit whose output depends not only on the present value of its input signals but on the sequence of past inputs the input history as well. These circuits are capable of remembering data.
