# 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 :-

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`
