Description
here we are taking three gates they are and ,not,or gates. in the and gate 1st pin i.e,A is connected to 15input and 4th pin i.e,B is connected to 14 input .and 5th pin i.e, is S is connectd to 13 input as well as it is connected to 1 st pin in not gate.now the output of S in not gate is connected to2 nd pin in and gate.now the output of 1,2 pins is connected to1 pin in or gate.and ouput of 4,5 pins in and gate is connected to 2nd pin or gate.now the ouput of 1,2 pins is connected to 0 ouput.we will get high values when all inputs i.e,a,b,s are in high or when a,b is high,and S is low then also ouput is high,or when a is high and remaining is in low then also ouput is high,when s,b are in high and a is low then also output is high and remaining all other cases ouput is low.
