Draw the resultant simplified logie cireuit. (i) A•barB+barA•B=Y (ii) (A+barb)•(barA+B)=Y |
Answer» Solution :(i) The required LOGIC diagram for the given Boolean expression is given in figure. Here the input B before applying to FIRST AND gate and input A before applying to second AND gate have been inverted. The output of these GATES are, therefore, `AbarB and barAB` RESPECTIVELY. These outputs are fed to OR gate which gives `T=AbarB+barAB` as shown in figure.  ii) The required logic diagram for the given Boolean expression is shown in figure. The input B to first OR gate and input A to second OR gate have been inverted. The output of these gates are, therefore, `A +barB and barA + B` as shown. These inputs when APPLIED to AND gate give the required output. `Y=(A+barb).(barA+B)`
