Question 6734 – UGC NET CS 2016 July- paper-3

Combinational circuits have no memory. Combinational circuits are defined as the time independent circuits which do not depend upon previous inputs to generate any output are termed as combinational circuits.
Examples: Encoder, Decoder, Multiplexer, Demultiplexer
Sequential circuits have memory. Sequential circuits are those which are dependent on clock cycles and depends on present as well as past inputs to generate any output.
Example: Flip-flops, Counters
