Boolean Expression

A 3-input majority logic gate has inputs $X, Y$ and $Z$. The output $F$ of the gate is logic ' 1 ' if two or more of the inputs are logic ' 1 '. The output $F$ is logic ' 0 ' if tw...

A 4-bit priority encoder has inputs $D_3, D_2, D_1$, and $D_0$ in descending order of priority. The two-bit output AB is generated as 00, 01, 10, and 11 corresponding to inputs $D_...

In a half-subtractor circuit with X and Y as inputs, the Borrow (M) and Difference (N = X - Y) are given by

The Boolean expression Y= $$\overline A \,\overline B \,\overline C \,D + \overline A BC\overline D + A\overline {B\,} \overline C \,D + AB\overline C \,\overline D $$
