Sequential Logic Vs Combinational Logic. Difference between combinational and sequential circuit. Sequential logic circuit unlike combinational logic circuits whose output depends upon the signals being applied to the inputs at that time sequential logic circuits have some form of memory built in to them so that they are able to take into account their previous input state as well as those at present.
Combinational logic is made up boolean logic gates where the output is the combination of the present input. Sequential circuits are those which are dependent on clock cycles and depends on present as well as past inputs to generate any output. Difference between combinational and sequential logic circuit.
Sequential circuit is the type of circuit where output not only relies on the current input but also depends on the previous output.
Combinational logic uses only the present inputs to determine the output while sequential logic uses both present inputs as well as previous outputs to determine the current input. These sequences are stored in memory units called flip flops or latches. So they are a time dependent circuit. Sequential circuits are those which are dependent on clock cycles and depends on present as well as past inputs to generate any output.
