sequential ckt. is a logic ckt whose output at any instant depend upon the past output or input value. combinational ckt is a ckt whose o/p at anyinstant depend upon only present input. The sequential ckt involves memory, combinational ckt has no memory
The main differance between sequential and combinational circuit is memory. The output of the sequential circuit depend upon the privious input and previous output of the circuit. While in case of combinational, current output is depend on current input only.
Sequential circuits are those crt whoese output depond on present input as well as on previos o/p,it has flip flops for temporary storage e.g flip flop & on the other hand the combinational logic crt ae those whoese output only depond on present input only e.g mux,de-mux,encoder,decoder
A sequential circuit uses flip flops. Unlike combinational logic, sequential circuits have state, which means basically, sequential circuits have memory.
The main difference between sequential circuits and combinational circuits is that sequential circuits compute their output based on input and state, and that the state is updated based on a clock. Combinational logic circuits implement Boolean functions, so they are functions only of their inputs, and are not based on clocks.
Combinational circuits are those whose output depends on only present inputs, sequential circuits are those whose output depends on both present inputs and previous outputs. in combinational circuits the output is synchronous to the input, that is when input is applied then output will come, in sequential circuits input data is synchronous to the clock.
Combinatorial circuits are those whose output depends on only present inputs but in Sequential circuits , there is concept of Memory Element .So in Sequential circuits output depends on both present inputs and previous outputs(stored in memory).
