4. COMBINATIONAL AND SEQUENTIONAL CIRCUITS Combinational logic refers to circuits whose output is a function of the  present value of the inputs  only . No memory element Only one input. Sequential logic circuits are those whose outputs are also dependent upon past inputs, and hence outputs Depending upon previous input. Memory element also present which stores output.

5. General Example of Combinational Logic: Last night before exams. General Example of Sequential Logic: Regular teaching.

6. COMBINATIONAL CIRCUITS : HALF ADDER. FULL ADDER. To add 2 binary digits. It has two inputs. Combinational Logic Circuits  are made up from basic logic  NAND ,  NOR  or  NOT  gates S  sum C  carry X  input no.1 Y  input no.1

7. NAND N OR +  OR gate. .  AND gate. AND

8. SEQUENTIONAL CIRCUITS :
