Refer following PPT for introduction of full adder
Full Adder Circuit.pptx
Design Steps:
Design Steps:
Step 1: Design a full adder using logic gates.
Step 2: Make copy of full adder so total three full adder circuit must be there
Step 3: Feed carry input to first LSB adder as 0
Step 4: Connect carry output of first adder to carry input to second adder and carry output of second adder to carry input to third adder.
Step 5: Now give respective bit input and observe the output
