Draw logic diagrams for the Boolean expressions given below. A * barB+ barA * B=Y

Answer»

Solution :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 gales are, therefore, `A barB` and `barA `B respectively. These OUTPUTS are FED to OR gate which gives `Y = A barB+ barA B `as shown in figure.
