4 bit Binary adder circuit
discussion with example.
4 bit Binary Adder introduction:
In this implementation, carry
of each full-
Lets start with the expressions for the FULL ADDER :-
Sum_out = [(in_x) XOR (in_y)] XOR [(carry_in)]
Carry_out = [(in_x) AND (in_y)] OR [ (in_x XOR in_y) AND carry_in ]
Next we will draw the circuit of 4 Bit
